Note:

The "W" in the "ISO year with ISO week" and "ISO year with ISO week and day" formats is case-sensitive, you can only use the upper case "W".

The "T" in the SOAP, XMRPC and WDDX formats is case-sensitive, you can only use the upper case "T".

The "Unix Timestamp" format sets the timezone to UTC.
