Notă:

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.

"Note that the localized format referred to in this list as "SOAP" is the ISO 8601 standard format for dates and times."

This isn't quite correct. ISO 8601 specifies numerous formats for both date and time; and for compound date and time, you can use any date format and any time format, with the two joined together by the letter "T".

If you wanted to write "2009T12", that would be noon on the first day of 2009, and it would be a valid ISO 8601 timestamp.
