timestampEndEnd timestamp.
Returns a numerically indexed array of
transition arrays on success, o false in caso di fallimento. 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.
