The
$timezoneparameter and the current timezone are ignored when the$datetimeparameter either is a UNIX timestamp (e.g.@946684800) or specifies a timezone (e.g.2010-01-28T15:00:00+02:00, or2010-07-05T06:00:00Z).

If an invalid Date/Time string is passed, DateMalformedStringException is thrown. Previous to PHP 8.3, this was Exception.
| Версія | Опис |
|---|---|
| 8.3.0 | Now throws DateMalformedStringException if an invalid string is passed, instead of Exception. |
| 7.1.0 | From now on microseconds are filled with actual value. Not with '00000'. |

"If $timezone is omitted or null, the current timezone will be used." - note, that timezone IS NOT equal offset, if its important for your application.
If default timezone = Europe/Moscow, then:
echo (new \DateTimeImmutable('2014-10'))->format(DATE_ATOM); // gives "2014-10-01T00:00:00+04:00"
echo (new \DateTimeImmutable('2014-11'))->format(DATE_ATOM); // gives "2014-11-01T00:00:00+03:00"
because of law changes (abolition of "summer time").
