    Значення, що повертаються

    Returns a numerically indexed array of transition arrays on success, або false в разі помилки. DateTimeZone objects wrapping type 1 (UTC offsets) and type 2 (abbreviations) do not contain any transitions, and calling this method on them will return false.

    If timestampBegin is given, the first entry in the returned array will contain a transition element at the time of timestampBegin.

    Transition Array Structure
    Key Type Description
    ts int Unix timestamp
    time string DateTimeInterface::ISO8601_EXPANDED (PHP 8.2 and later), or DateTimeInterface::ISO8601 (PHP 8.1 and lower) time string
    offset int Offset to UTC in seconds
    isdst bool Whether daylight saving time is active
    abbr string Timezone abbreviation
