Bug 158947 the error of the datetime type conversion
Description: Now we input "Jan 13, 2003 12:00 AM GMT0100" into the parameter as a default value. The time is not transformed base on the time zone "GMT0100". The time should be transformed. And the other form input e.g. "SUN Jan 13, 2003 12:00 AM GMT0100" should be identified correctly. Step to reproduce: 1. new a report and create a report parameter 2. choose the date type "DateTime" 3. input value "SUN Jan 13, 2003 12:00 AM GMT0100" as default value,ok to finish 4. error message appear 5. input value "SUN Jan 13, 2003 12:00 AM" and click ok Actuate result: the parameter value is still "01/13/2003 12:00:00 AM" Excepted result: the datetime value should be transformed base on the time zone.
