    过程化风格
    intlcal_set_skipped_wall_time_option(IntlCalendar$cal,int $wallTimeOption): bool

    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.

    参数

    $cal

    The IntlCalendar resource.

    $wallTimeOption

    One of the constants IntlCalendar::WALLTIME_FIRST,IntlCalendar::WALLTIME_LAST or IntlCalendar::WALLTIME_NEXT_VALID.

    返回值

    Returns TRUE on success. Failure can only happen due to invalid parameters.

    范例
