IntlCalendar::setSkippedWallTimeOption — Set behavior for handling skipped wall times at positive timezone offset transitions
面向对象风格
$option
) : bool过程化风格
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.
This function requires ICU 4.9 or later.
