Time zone abbreviation.
Offset from GMT in seconds. Defaults to -1 which means that first found time zone corresponding to abbr
is returned. Otherwise exact offset is searched and only if not found then the first time zone with any offset is returned.
Daylight saving time indicator. Defaults to -1, which means that whether the time zone has daylight saving or not is not taken into consideration when searching. If this is set to 1, then the gmtOffset
is assumed to be an offset with daylight saving in effect; if 0, then gmtOffset
is assumed to be an offset without daylight saving in effect. If abbr
doesn't exist then the time zone is searched solely by the gmtOffset
and isdst
.
Returns time zone name on success or FALSE
on failure.
<?php echo timezone_name_from_abbr("CET") . "\n"; echo timezone_name_from_abbr("", 3600, 0) . "\n"; ?>
