Returns new DateTime object

public function DateTime::__construct(string $datetime = "now", ?DateTimeZone $timezone = null)

Like DateTimeImmutable::__construct() but works with DateTime. Consider using the DateTimeImmutable and features instead.

Returns a new DateTime object.

datetime: A date/time string. Valid formats are explained in Date and Time Formats.
Enter "now" here to obtain the current time when using the timezone parameter.
timezone: A DateTimeZone object representing the timezone of datetime. If timezone is omitted or null, the current timezone will be used.
Note: The timezone parameter and the current timezone are ignored when the datetime parameter either is a UNIX timestamp (e.g. @946684800) or specifies a timezone (e.g. 2010-01-28T15:00:00+02:00).

Returns a new DateTime instance.

If an invalid Date/Time string is passed, DateMalformedStringException is thrown. Previous to PHP 8.3, this was Exception.

Version	Description
8.3.0	Now throws DateMalformedStringException if an invalid string is passed, instead of Exception.
