IntlCalendar::setSkippedWallTimeOption — Set behavior for handling skipped wall times at positive timezone offset transitions
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.
