Descrizione

timezone_name_from_abbr(string $abbr, int $utcOffset = -1, int $isDST = -1): string|false

Elenco dei parametri

abbr

Time zone abbreviation.

utcOffset

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 utcOffset is assumed to be an offset with daylight saving in effect; if 0, then utcOffset 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 utcOffset and isDST.

Valori restituiti

Returns time zone name on success o false in caso di fallimento.
