DateTime::__constructReturns new DateTime object


public 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.



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.


A DateTimeZone object representing the timezone of $datetime.

If $timezone is omitted or null, the current timezone will be used.


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).

Return Values

Returns a new DateTime instance. Procedural style returns false on failure.
