Changelog

Version	Description
7.2.0	The class constants of DateTime are now defined on DateTimeInterface.
7.0.0	Added constants: DATE_RFC3339_EXTENDED and DateTime::RFC3339_EXTENDED.
5.5.0	The class now implements DateTimeInterface.
5.4.24	The COOKIE constant was changed to reflect RFC 1036 using a four digit year rather than a two digit year (RFC 850) as prior versions.
5.2.2	DateTime object comparison with the comparison operators changed to work as expected. Previously, all DateTime objects were considered equal (using ==).

DateTime::__construct — Returns new DateTime object
DateTime::createFromFormat — Parses a time string according to a specified format

DateTime::modify — Alters the timestamp
DateTime::__set_state — The __set_state handler
DateTime::setDate — Sets the date
DateTime::setISODate — Sets the ISO date
DateTime::setTime — Sets the time
DateTime::setTimestamp — Sets the date and time based on an Unix timestamp
