IntlCalendar::setSkippedWallTimeOption

Set behavior for handling skipped wall times at positive timezone offset transitions

Description

Object-oriented style

public true IntlCalendar::setSkippedWallTimeOption(int $option)

Procedural style

true intlcal_set_skipped_wall_time_option(IntlCalendar $calendar, int $option)

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.

Parameters

option

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