timezone_name_from_abbrReturns the timezone name from abbreviation

说明

string timezone_name_from_abbr ( string $abbr [, int $gmtOffset = -1 [, int $isdst = -1 ]] )

参数

abbr

Time zone abbreviation.

gmtOffset

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.

isdst

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.

返回值

Returns time zone name on success 或者在失败时返回 FALSE.
