  Date.parse return value is limited to specified time value maximum range
info: |
  Date.parse ( string )

  parse interprets the resulting String as a date and time; it returns a
  Number, the UTC time value corresponding to the date and time.

  A Date object contains a Number indicating a particular instant in time to
  within a millisecond. Such a Number is called a time value.

  The actual range of times supported by ECMAScript Date objects is slightly
  smaller: exactly -100,000,000 days to 100,000,000 days measured relative to
  midnight at the beginning of 01 January, 1970 UTC. This gives a range of
  8,640,000,000,000,000 milliseconds to either side of 01 January, 1970 UTC.
