Parameters

string $abbreviation: Time zone abbreviation.

int $offset: Offset from GMT in seconds. Defaults to -1 which means that first found time zone corresponding to abbreviation is returned. Otherwise exact offset is searched and only if not found then the first time zone with any offset is returned.

        if ($original !== $is_daylight_saving_time) {
            return new JsonResponse(FALSE);
        }
    }
    // An abbreviation of "0" passed in the callback arguments should be
    // interpreted as the empty string.
