* Overridden constructor.

* @param $time
* time string, flexible format including timestamp.
* @param $tz
* PHP DateTimeZone object, string or NULL allowed, defaults to site timezone.
* @param $format
* PHP date() type format for parsing. Doesn't support timezones; if you have a timezone, send NULL
* and the default constructor method will hopefully parse it.
* $format is recommended in order to use negative or large years, which php's parser fails on.
