IntlCalendar::setSkippedWallTimeOption — Set behavior for handling skipped wall times at positive timezone offset transitions
$wallTimeOption
)
Sets the current strategy for dealing with wall times that are skipped
whenever the clock is forwarded during dailight saving time start transitions.
The default value is IntlCalendar::WALLTIME_LAST (take
it as being the same instant as the one when the wall time is one hour
more). Alternative values are
IntlCalendar::WALLTIME_FIRST (same instant as the one
with a wall time of one hour less) and
IntlCalendar::WALLTIME_NEXT_VALID (same instant as
when DST begins).
This affects only the instant represented by the calendar (as reported by IntlCalendar::getTime()), the field values will not be rewritten accordingly.
The calendar must be lenient for this option to have any effect, otherwise attempting to set a non-existing time will cause an error.
wallTimeOption
One of the constants IntlCalendar::WALLTIME_FIRST,
IntlCalendar::WALLTIME_LAST or
IntlCalendar::WALLTIME_NEXT_VALID.
Returns TRUE on success. Failure can only happen due to invalid parameters.
See the example on IntlCalendar::getSkippedWallTimeOption().
