fn.adjustDateTimeToTimezone( arg as Date?, [timezone as xs.dayTimeDuration?] ) as Date?
Summary
Adjusts an xs:dateTime value to a specific timezone, or to no timezone at all. If $timezone is the empty sequence, returns an xs:dateTime without a timezone. Otherwise, returns an xs:dateTime with a timezone.
If $timezone is not specified, then $timezone is the value of the implicit timezone in the dynamic context.
If $arg is the empty sequence, then the result is the empty sequence.
A dynamic error is raised [err:FODT0003] if $timezone is less than -PT14H or greater than PT14H or if does not contain an integral number of minutes.
If $arg does not have a timezone component and $timezone is the empty sequence, then the result is $arg.
If $arg does not have a timezone component and $timezone is not the empty sequence, then the result is $arg with $timezone as the timezone component.
If $arg has a timezone component and $timezone is the empty sequence, then the result is the localized value of $arg without its timezone component.
If $arg has a timezone component and $timezone is not the empty sequence, then the result is an xs:dateTime value with a timezone component of $timezone that is equal to $arg.
| Parameters | |
|---|---|
| arg | The dateTime to adjust to the new timezone. |
| timezone | The new timezone for the dateTime. |
Example
Assume the dynamic context provides an implicit timezone
of -05:00 (-PT5H0M).
