It's a single, unambiguous Date and Time format. No it's not unambigious: $ php -r 'date_default_timezone_set("Europe/London"); echo date_create()->format(DateTime::ISO8601), "\n";' 2012-09-02T18:17:36+0100 $ php -r 'date_default_timezone_set("Africa/Niamey"); echo date_create()->format(DateTime::ISO8601), "\n";' 2012-09-02T18:19:05+0100 vs: $ php -r 'date_default_timezone_set("Africa/Niamey"); echo date_create("2012-12-31")->format(DateTime::ISO8601), "\n";' 2012-12-31T00:00:00+0100 ^^^^^ $ php -r 'date_default_timezone_set("Europe/London"); echo date_create("2012-12-31")->format(DateTime::ISO8601), "\n";' 2012-12-31T00:00:00+0000 ^^^^^ cheers, Derick
