ISO 8601:2004 is a fairly broad standard containing a large number of 
date and time formats. The W3C advocates using the T (and the ISO 
standard itself can only be downloaded after paying for it), but some 
resources at least suggest that using a space instead of a T also yields 
a valid ISO 8601 date/time format.
