/++ $(LUCKY Regular expressions) are a commonly used method of pattern matching on strings, with $(I regex) being a catchy word for a pattern in this domain specific language. Typical problems usually solved by regular expressions include validation of user input and the ubiquitous find $(AMP) replace in text processing utilities. $(SECTION Synopsis) --- import std.regex; import std.stdio; void main() { // Print out all possible dd/mm/yy(yy) dates found in user input. auto r = regex(r"\b[0-9][0-9]?/[0-9][0-9]?/[0-9][0-9](?:[0-9][0-9])?\b"); foreach(line; stdin.byLine) { // matchAll() returns a range that can be iterated // to get all subsequent matches. foreach(c; matchAll(line, r)) writeln(c.hit); } } ... // Create a static regex at compile-time, which contains fast native code. auto ctr = ctRegex!(`^.*/([^/]+)/?$`); // It works just like a normal regex: auto c2 = matchFirst("foo/bar", ctr); // First match found here, if any assert(!c2.empty); // Be sure to check if there is a match before examining contents! assert(c2[1] == "bar"); // Captures is a range of submatches: 0 = full match. ... // The result of the $(D matchAll) is directly testable with if/assert/while. // e.g. test if a string consists of letters: assert(matchFirst("Letter", `^\p{L}+$`)); --- $(SECTION Syntax and general information) The general usage guideline is to keep regex complexity on the side of simplicity, as its capabilities reside in purely character-level manipulation. As such it's ill-suited for tasks involving higher level invariants like matching an integer number $(U bounded) in an [a,b] interval. Checks of this sort of are better addressed by additional post-processing. The basic syntax shouldn't surprise experienced users of regular expressions. For an introduction to $(D std.regex) see a $(WEB dlang.org/regular-expression.html, short tour) of the module API and its abilities. There are other web resources on regular expressions to help newcomers, and a good $(WEB www.regular-expressions.info, reference with tutorial) can easily be found. This library uses a remarkably common ECMAScript syntax flavor with the following extensions: $(UL $(LI Named subexpressions, with Python syntax. ) $(LI Unicode properties such as Scripts, Blocks and common binary properties e.g Alphabetic, White_Space, Hex_Digit etc.) $(LI Arbitrary length and complexity lookbehind, including lookahead in lookbehind and vise-versa.) ) $(REG_START Pattern syntax ) $(I std.regex operates on codepoint level, 'character' in this table denotes a single Unicode codepoint.) $(REG_TABLE $(REG_TITLE Pattern element, Semantics ) $(REG_TITLE Atoms, Match single characters ) $(REG_ROW any character except [{|*+?()^$, Matches the character itself. ) $(REG_ROW ., In single line mode matches any character.

Greedy version - tries as many times as possible, but no more than m times. ) $(REG_ROW {n$(COMMA)m}?, Matches previous character/subexpression n to m times. Lazy version - stops as early as possible, but no less then n times.) $(REG_TITLE Other, Subexpressions $(AMP) alternations ) $(REG_ROW (regex), Matches subexpression regex, saving matched portion of text for later retrieval. ) $(REG_ROW (?:regex), Matches subexpression regex, $(U not) saving matched portion of text. Useful to speed up matching. ) $(REG_ROW A|B, Matches subexpression A, or failing that, matches B. ) $(REG_ROW (?P$(LT)name$(GT)regex), Matches named subexpression regex labeling it with name 'name'. When referring to a matched portion of text, names work like aliases in addition to direct numbers. ) $(REG_TITLE Assertions, Match position rather than character ) $(REG_ROW ^, Matches at the begining of input or line (in multiline mode).) $(REG_ROW $, Matches at the end of input or line (in multiline mode). ) $(REG_ROW \b, Matches at word boundary. ) $(REG_ROW \B, Matches when $(U not) at word boundary. ) $(REG_ROW (?=regex), Zero-width lookahead assertion. Matches at a point where the subexpression regex could be matched starting from the current position. ) $(REG_ROW (?!regex), Zero-width negative lookahead assertion. Matches at a point where the subexpression regex could $(U not) be matched starting from the current position. ) $(REG_ROW (?<=regex), Zero-width lookbehind assertion. Matches at a point where the subexpression regex could be matched ending at the current position (matching goes backwards). ) $(REG_ROW (?<!regex), Zero-width negative lookbehind assertion. Matches at a point where the subexpression regex could $(U not) be matched ending at the current position (matching goes backwards). ) ) $(REG_START Character classes ) $(REG_TABLE $(REG_TITLE Pattern element, Semantics ) $(REG_ROW Any atom, Has the same meaning as outside of a character class.) $(REG_ROW a-z, Includes characters a, b, c, ..., z. ) $(REG_ROW [a||b]$(COMMA) [a--b]$(COMMA) [a~~b]$(COMMA) [a$(AMP)$(AMP)b], Where a, b are arbitrary classes, means union, set difference, symmetric set difference, and intersection respectively. $(I Any sequence of character class elements implicitly forms a union.) ) ) $(REG_START Regex flags ) $(REG_TABLE $(REG_TITLE Flag, Semantics ) $(REG_ROW g, Global regex, repeat over the whole input. ) $(REG_ROW i, Case insensitive matching. ) $(REG_ROW m, Multi-line mode, match ^, $ on start and end line separators as well as start and end of input.) $(REG_ROW s, Single-line mode, makes . match '\n' and '\r' as well. ) $(REG_ROW x, Free-form syntax, ignores whitespace in pattern, useful for formatting complex regular expressions. ) ) $(SECTION Unicode support) This library provides full Level 1 support* according to $(WEB unicode.org/reports/tr18/, UTS 18). Specifically: $(UL $(LI 1.1 Hex notation via any of \uxxxx, \U00YYYYYY, \xZZ.) $(LI 1.2 Unicode properties.) $(LI 1.3 Character classes with set operations.) $(LI 1.4 Word boundaries use the full set of "word" characters.) $(LI 1.5 Using simple casefolding to match case insensitively across the full range of codepoints.) $(LI 1.6 Respecting line breaks as any of \u000A | \u000B | \u000C | \u000D | \u0085 | \u2028 | \u2029 | \u000D\u000A.) $(LI 1.7 Operating on codepoint level.) ) *With exception of point 1.1.1, as of yet, normalization of input is expected to be enforced by user. $(SECTION Replace format string) A set of functions in this module that do the substitution rely on a simple format to guide the process. In particular the table below applies to the $(D format) argument of $(LREF replaceFirst) and $(LREF replaceAll). The format string can reference parts of match using the following notation. $(REG_TABLE $(REG_TITLE Format specifier, Replaced by ) $(REG_ROW $$(AMP), the whole match. ) $(REG_ROW $(DOLLAR)$(BACKTICK), part of input $(I preceding) the match. ) $(REG_ROW $', part of input $(I following) the match. ) $(REG_ROW $$, '$' character. ) $(REG_ROW \c $(COMMA) where c is any character, the character c itself. ) $(REG_ROW \\, '\' character. ) $(REG_ROW $(DOLLAR)1 .. $(DOLLAR)99, submatch number 1 to 99 respectively. ) ) $(SECTION Slicing and zero memory allocations orientation) All matches returned by pattern matching functionality in this library are slices of the original input. The notable exception is the $(D replace) family of functions that generate a new string from the input. In cases where producing the replacement is the ultimate goal $(LREF replaceFirstInto) and $(LREF replaceAllInto) could come in handy as functions that avoid allocations even for replacement.

//Written in the D programming language /++ Module containing Date/Time functionality. This module provides: $(UL $(LI Types to represent points in time: $(D SysTime), $(D Date), $(D TimeOfDay), and $(D DateTime).) $(LI Types to represent intervals of time.) $(LI Types to represent ranges over intervals of time.) $(LI Types to represent time zones (used by $(D SysTime)).) $(LI A platform-independent, high precision stopwatch type: $(D StopWatch)) $(LI Benchmarking functions.) $(LI Various helper functions.) ) Closely related to std.datetime is <a href="core_time.html">$(D core.time)</a>, and some of the time types used in std.datetime come from there - such as $(CXREF time, Duration), $(CXREF time, TickDuration), and $(CXREF time, FracSec). core.time is publically imported into std.datetime, it isn't necessary to import it separately. Three of the main concepts used in this module are time points, time durations, and time intervals. A time point is a specific point in time. e.g. January 5th, 2010 or 5:00. A time duration is a length of time with units. e.g. 5 days or 231 seconds. A time interval indicates a period of time associated with a fixed point in time. It is either two time points associated with each other, indicating the time starting at the first point up to, but not including, the second point - e.g. [January 5th, 2010 - March 10th, 2010$(RPAREN) - or it is a time point and a time duration associated with one another. e.g. January 5th, 2010 and 5 days, indicating [January 5th, 2010 - January 10th, 2010$(RPAREN). Various arithmetic operations are supported between time points and durations (e.g. the difference between two time points is a time duration), and ranges can be gotten from time intervals, so range-based operations may be done on a series of time points. The types that the typical user is most likely to be interested in are $(D Date) (if they want dates but don't care about time), $(D DateTime) (if they want dates and times but don't care about time zones), $(D SysTime) (if they want the date and time from the OS and/or do care about time zones), and StopWatch (a platform-independent, high precision stop watch). $(D Date) and $(D DateTime) are optimized for calendar-based operations, while $(D SysTime) is designed for dealing with time from the OS. Check out their specific documentation for more details. To get the current time, use $(D Clock.currTime). It will return the current time as a $(D SysTime). To print it, $(D toString) is sufficient, but if using $(D toISOString), $(D toISOExtString), or $(D toSimpleString), use the corresponding $(D fromISOString), $(D fromISOExtString), or $(D fromISOExtString) to create a $(D SysTime) from the string. -------------------- auto currentTime = Clock.currTime(); auto timeString = currentTime.toISOExtString(); auto restoredTime = SysTime.fromISOExtString(timeString); -------------------- Various functions take a string (or strings) to represent a unit of time (e.g. $(D convert!("days", "hours")(numDays))). The valid strings to use with such functions are $(D "years"), $(D "months"), $(D "weeks"), $(D "days"), $(D "hours"), $(D "minutes"), $(D "seconds"), $(D "msecs") (milliseconds), $(D "usecs") (microseconds), $(D "hnsecs") (hecto-nanoseconds - i.e. 100 ns), or some subset thereof. There are a few functions in core.time which take $(D "nsecs"), but because nothing in std.datetime has precision greater than hnsecs, and very little in core.time does, no functions in std.datetime accept $(D "nsecs"). To remember which units are abbreviated and which aren't, all units seconds and greater use their full names, and all sub-second units are abbreviated (since they'd be rather long if they weren't).

If overflow is allowed (as is the default), then the month will be incremented accordingly (so, February 29th 2001 would become March 1st 2001, and June 31st 2000 would become July 1st 2000). If overflow is not allowed, then the day will be adjusted to the last valid day in that month (so, February 29th 2001 would become February 28th 2001 and June 31st 2000 would become June 30th 2000).

One example of its use is $(D Interval)'s $(D expand) function which uses it to indicate whether the interval should be expanded backwards (into the past), forwards (into the future), or both. +/ enum Direction { /// Backward. bwd, /// Forward. fwd, /// Both backward and forward. both } /++ Used to indicate whether $(D popFront) should be called immediately upon creating a range. The idea is that for some functions used to generate a range for an interval, $(D front) is not necessarily a time point which would ever be generated by the range. To get the first time point in the range to match what the function generates, then use $(D PopFirst.yes) to indicate that the range should have $(D popFront) called on it before the range is returned so that $(D front) is a time point which the function would generate. For instance, if the function used to generate a range of time points generated successive Easters (i.e. you're iterating over all of the Easters within the interval), the initial date probably isn't an Easter. Using $(D PopFirst.yes) would tell the function which returned the range that $(D popFront) was to be called so that front would then be an Easter - the next one generated by the function (which when iterating forward would be the Easter following the original $(D front), while when iterating backward, it would be the Easter prior to the original $(D front)). If $(D PopFirst.no) were used, then $(D front) would remain the original time point and it would not necessarily be a time point which would be generated by the range-generating function (which in many cases is exactly what is desired - e.g. if iterating over every day starting at the beginning of the interval). +/ enum PopFirst { /// No, don't call popFront() before returning the range. no, /// Yes, call popFront() before returning the range. yes } /++ Used by StopWatch to indicate whether it should start immediately upon construction. +/ enum AutoStart { /// No, don't start the StopWatch when it is constructed. no, /// Yes, do start the StopWatch when it is constructed. yes } /++ Array of the strings representing time units, starting with the smallest unit and going to the largest.

Unlike $(D DateTime), the time zone is an integral part of $(D SysTime) (though for local time applications, time zones can be ignored and it will work, since it defaults to using the local time zone). It holds its internal time in std time (hnsecs since midnight, January 1st, 1 A.D. UTC), so it interfaces well with the system time. However, that means that, unlike $(D DateTime), it is not optimized for calendar-based operations, and getting individual units from it such as years or days is going to involve conversions and be less efficient. For calendar-based operations that don't care about time zones, then $(D DateTime) would be the type to use. For system time, use $(D SysTime). $(D Clock.currTime) will return the current time as a $(D SysTime). To convert a $(D SysTime) to a $(D Date) or $(D DateTime), simply cast it. To convert a $(D Date) or $(D DateTime) to a $(D SysTime), use $(D SysTime)'s constructor, and pass in the intended time zone with it (or don't pass in a $(D TimeZone), and the local time zone will be used). Be aware, however, that converting from a $(D DateTime) to a $(D SysTime) will not necessarily be 100% accurate due to DST (one hour of the year doesn't exist and another occurs twice). To not risk any conversion errors, keep times as $(D SysTime)s. Aside from DST though, there shouldn't be any conversion problems. For using time zones other than local time or UTC, use $(D PosixTimeZone) on Posix systems (or on Windows, if providing the TZ Database files), and use $(D WindowsTimeZone) on Windows systems. The time in $(D SysTime) is kept internally in hnsecs from midnight, January 1st, 1 A.D. UTC. Conversion error cannot happen when changing the time zone of a $(D SysTime). $(D LocalTime) is the $(D TimeZone) class which represents the local time, and $(D UTC) is the $(D TimeZone) class which represents UTC. $(D SysTime) uses $(D LocalTime) if no $(D TimeZone) is provided. For more details on time zones, see the documentation for $(D TimeZone), $(D PosixTimeZone), and $(D WindowsTimeZone). $(D SysTime)'s range is from approximately 29,000 B.C. to approximately 29,000 A.D. +/ struct SysTime { public: /++ Params: dateTime = The $(D DateTime) to use to set this $(D SysTime)'s internal std time.

A negative number will subtract. The difference between rolling and adding is that rolling does not affect larger units. Rolling a $(D SysTime) 12 months gets the exact same $(D SysTime). However, the days can still be affected due to the differing number of days in each month. Because there are no units larger than years, there is no difference between adding and rolling years. Params: units = The type of units to add ("years" or "months"). value = The number of months or years to add to this $(D SysTime). allowOverflow = Whether the days should be allowed to overflow, causing the month to increment.

A negative number will subtract. The difference between rolling and adding is that rolling does not affect larger units. For instance, rolling a $(D SysTime) one year's worth of days gets the exact same $(D SysTime). Accepted units are $(D "days"), $(D "minutes"), $(D "hours"), $(D "minutes"), $(D "seconds"), $(D "msecs"), $(D "usecs"), and $(D "hnsecs"). Note that when rolling msecs, usecs or hnsecs, they all add up to a second. So, for example, rolling 1000 msecs is exactly the same as rolling 100,000 usecs.

To get the difference in years, subtract the year property of two $(D SysTime)s. To get the difference in days or weeks, subtract the $(D SysTime)s themselves and use the $(D Duration) that results. Because converting between months and smaller units requires a specific date (which $(D Duration)s don't have), getting the difference in months requires some math using both the year and month properties, so this is a convenience function for getting the difference in months. Note that the number of days in the months or how far into the month either date is is irrelevant. It is the difference in the month property combined with the difference in years * 12.

Whitespace is stripped from the given string. The exact format is exactly as described in $(D toSimpleString) except that trailing zeroes are permitted - including having fractional seconds with all zeroes. However, a decimal point with nothing following it is invalid. If there is no time zone in the string, then $(D LocalTime) is used. If the time zone is "Z", then $(D UTC) is used. Otherwise, a $(LREF SimpleTimeZone) which corresponds to the given offset from UTC is used. To get the returned $(D SysTime) to be a particular time zone, pass in that time zone and the $(D SysTime) to be returned will be converted to that time zone (though it will still be read in as whatever time zone is in its string). The accepted formats for time zone offsets are +H, -H, +HH, -HH, +H:MM, -H:MM, +HH:MM, and -HH:MM. Params: simpleString = A string formatted in the way that $(D toSimpleString) formats dates and times. tz = The time zone to convert the given time to (no conversion occurs if null). Throws: $(D DateTimeException) if the given string is not in the ISO format or if the resulting $(D SysTime) would not be valid.

A negative number will subtract. The difference between rolling and adding is that rolling does not affect larger units. Rolling a $(D Date) 12 months gets the exact same $(D Date). However, the days can still be affected due to the differing number of days in each month. Because there are no units larger than years, there is no difference between adding and rolling years.

To get the difference in years, subtract the year property of two $(D SysTime)s. To get the difference in days or weeks, subtract the $(D SysTime)s themselves and use the $(D Duration) that results. Because converting between months and smaller units requires a specific date (which $(D Duration)s don't have), getting the difference in months requires some math using both the year and month properties, so this is a convenience function for getting the difference in months. Note that the number of days in the months or how far into the month either date is is irrelevant. It is the difference in the month property combined with the difference in years * 12.

The range's $(D front) is the interval's $(D begin). $(D_PARAM func) is used to generate the next $(D front) when $(D popFront) is called. If $(D_PARAM popFirst) is $(D PopFirst.yes), then $(D popFront) is called before the range is returned (so that $(D front) is a time point which $(D_PARAM func) would generate). If $(D_PARAM func) ever generates a time point less than or equal to the current $(D front) of the range, then a $(D DateTimeException) will be thrown. There are helper functions in this module which generate common delegates to pass to $(D fwdRange). Their documentation starts with "Range-generating function," to make them easily searchable. Params: func = The function used to generate the time points of the range over the interval. popFirst = Whether $(D popFront) should be called on the range before returning it. Throws: $(D DateTimeException) if this interval is empty. Warning: $(D_PARAM func) must be logically pure. Ideally, $(D_PARAM func) would be a function pointer to a pure function, but forcing $(D_PARAM func) to be pure is far too restrictive to be useful, and in order to have the ease of use of having functions which generate functions to pass to $(D fwdRange), $(D_PARAM func) must be a delegate. If $(D_PARAM func) retains state which changes as it is called, then some algorithms will not work correctly, because the range's $(D save) will have failed to have really saved the range's state. To avoid such bugs, don't pass a delegate which is not logically pure to $(D fwdRange). If $(D_PARAM func) is given the same time point with two different calls, it must return the same result both times. Of course, none of the functions in this module have this problem, so it's only relevant for custom delegates.

The range's $(D front) is the interval's $(D end). $(D_PARAM func) is used to generate the next $(D front) when $(D popFront) is called. If $(D_PARAM popFirst) is $(D PopFirst.yes), then $(D popFront) is called before the range is returned (so that $(D front) is a time point which $(D_PARAM func) would generate). If $(D_PARAM func) ever generates a time point greater than or equal to the current $(D front) of the range, then a $(D DateTimeException) will be thrown.

Throws: $(D DateTimeException) if this interval is empty. Warning: $(D_PARAM func) must be logically pure. Ideally, $(D_PARAM func) would be a function pointer to a pure function, but forcing $(D_PARAM func) to be pure is far too restrictive to be useful, and in order to have the ease of use of having functions which generate functions to pass to $(D fwdRange), $(D_PARAM func) must be a delegate. If $(D_PARAM func) retains state which changes as it is called, then some algorithms will not work correctly, because the range's $(D save) will have failed to have really saved the range's state. To avoid such bugs, don't pass a delegate which is not logically pure to $(D fwdRange). If $(D_PARAM func) is given the same time point with two different calls, it must return the same result both times. Of course, none of the functions in this module have this problem, so it's only relevant for custom delegates.

Returns a delegate which returns the next time point with the given month which would be reached by adding months to the given time point. So, using this delegate allows iteration over successive time points which are in the same month but different years. For example, iterate over each successive December 25th in an interval by starting with a date which had the 25th as its day and passed $(D Month.dec) to $(D everyMonth) to create the delegate. Since it wouldn't really make sense to be iterating over a specific month and end up with some of the time points in the succeeding month or two years after the previous time point, $(D AllowDayOverflow.no) is always used when calculating the next time point. Params: dir = The direction to iterate in. If passing the return value to $(D fwdRange), use $(D Direction.fwd).

Returns a delegate which returns the next time point which is the given number of years, month, and duration later. The difference between this version of $(D everyDuration) and the version which just takes a $(D Duration) is that this one also takes the number of years and months (along with an $(D AllowDayOverflow) to indicate whether adding years and months should allow the days to overflow). Note that if iterating forward, $(D add!"years"()) is called on the given time point, then $(D add!"months"()), and finally the duration is added to it. However, if iterating backwards, the duration is added first, then $(D add!"months"()) is called, and finally $(D add!"years"()) is called. That way, going backwards generates close to the same time points that iterating forward does, but since adding years and months is not entirely reversible (due to possible day overflow, regardless of whether $(D AllowDayOverflow.yes) or $(D AllowDayOverflow.no) is used), it can't be guaranteed that iterating backwards will give the same time points as iterating forward would have (even assuming that the end of the range is a time point which would be returned by the delegate when iterating forward from $(D begin)). Params: dir = The direction to iterate in. If passing the return value to $(D fwdRange), use $(D Direction.fwd). If passing it to $(D bwdRange), use $(D Direction.bwd). years = The number of years to add to the time point passed to the delegate. months = The number of months to add to the time point passed to the delegate. allowOverflow = Whether the days should be allowed to overflow on $(D begin) and $(D end), causing their month to increment. duration = The duration to add to the time point passed to the delegate.

However, when it is constructed, it is given a function, $(D func), which is used to generate the time points which are iterated over. $(D func) takes a time point and returns a time point of the same type. For instance, to iterate over all of the days in the interval $(D Interval!Date), pass a function to $(D Interval)'s $(D fwdRange) where that function took a $(D Date) and returned a $(D Date) which was one day later. That function would then be used by $(D IntervalRange)'s $(D popFront) to iterate over the $(D Date)s in the interval. If $(D dir == Direction.fwd), then a range iterates forward in time, whereas if $(D dir == Direction.bwd), then it iterates backwards in time. So, if $(D dir == Direction.fwd) then $(D front == interval.begin), whereas if $(D dir == Direction.bwd) then $(D front == interval.end). $(D func) must generate a time point going in the proper direction of iteration, or a $(D DateTimeException) will be thrown. So, to iterate forward in time, the time point that $(D func) generates must be later in time than the one passed to it. If it's either identical or earlier in time, then a $(D DateTimeException) will be thrown. To iterate backwards, then the generated time point must be before the time point which was passed in. If the generated time point is ever passed the edge of the range in the proper direction, then the edge of that range will be used instead. So, if iterating forward, and the generated time point is past the interval's $(D end), then $(D front) becomes $(D end). If iterating backwards, and the generated time point is before $(D begin), then $(D front) becomes $(D begin). In either case, the range would then be empty. Also note that while normally the $(D begin) of an interval is included in it and its $(D end) is excluded from it, if $(D dir == Direction.bwd), then $(D begin) is treated as excluded and $(D end) is treated as included. This allows for the same behavior in both directions. This works because none of $(D Interval)'s functions which care about whether $(D begin) or $(D end) is included or excluded are ever called by $(D IntervalRange). $(D interval) returns a normal interval, regardless of whether $(D dir == Direction.fwd) or if $(D dir == Direction.bwd), so any $(D Interval) functions which are called on it which care about whether $(D begin) or $(D end) are included or excluded will treat $(D begin) as included and $(D end) as excluded. +/ struct IntervalRange(TP, Direction dir) if(isTimePoint!TP && dir != Direction.both) { public: /++ Params: rhs = The $(D IntervalRange) to assign to this one. +/ /+ref+/ IntervalRange opAssign(ref IntervalRange rhs) pure nothrow { _interval = rhs._interval; _func = rhs._func; return this; } /++ Whether this $(D IntervalRange) is empty. +/ @property bool empty() const pure nothrow { return _interval.empty; } /++ The first time point in the range.

To use the TZ Database, use $(LREF PosixTimeZone) (which reads its information from the TZ Database files on disk) on Windows by providing the TZ Database files and telling $(D PosixTimeZone.getTimeZone) where the directory holding them is. The TZ Database files and Windows' time zone information frequently do not match. Windows has many errors with regards to when DST switches occur (especially for historical dates). Also, the TZ Database files include far more time zones than Windows does. So, for accurate time zone information, use the TZ Database files with $(LREF PosixTimeZone) rather than $(D WindowsTimeZone).

Be aware of the differences when selecting a method. $(D WindowsTimeZone) does not exist on Posix systems. To get a $(D WindowsTimeZone), either call $(D WindowsTimeZone.getTimeZone) or call $(D TimeZone.getTimeZone) (which will give a $(LREF PosixTimeZone) on Posix systems and a $(D WindowsTimeZone) on Windows systems).

It provides the * facilities for registering and managing all fundamental data types, * user-defined object and interface types. Before using any GType * or GObject functions, g_type_init() must be called to initialize the * type system. * For type creation and registration purposes, all types fall into one of * two categories: static or dynamic. Static types are never loaded or * unloaded at run-time as dynamic types may be. Static types are created * with g_type_register_static() that gets type specific information passed * in via a GTypeInfo structure. * Dynamic types are created with g_type_register_dynamic() which takes a * GTypePlugin structure instead. The remaining type information (the * GTypeInfo structure) is retrieved during runtime through GTypePlugin * and the g_type_plugin_*() API. * These registration functions are usually called only once from a * function whose only purpose is to return the type identifier for a * specific class. Once the type (or class or interface) is registered, * it may be instantiated, inherited, or implemented depending on exactly * what sort of type it is. * There is also a third registration function for registering fundamental * types called g_type_register_fundamental() which requires both a GTypeInfo * structure and a GTypeFundamentalInfo structure but it is seldom used * since most fundamental types are predefined rather than user-defined. * A final word about type names. * Such an identifier needs to be at least three characters long.
