Yep, no one ever updated the Reuters submission, but that's the datetime format specified in W3C XML Schema, etc. So don't be fooled by the unassertive nature or the document - the format itself it a strong standard and is already used widely > > Unfortunately it can not be produced by shell scripts using the "date" > > command. > > The full format used in the note, save the fractional part of a second, > can be specified as: > > $ date '+%Y-%m-%dT%H-%M-%S%:z' > 2006-01-08T19-29-44+00:00 It's a pity about the fractional part - it's useful when you need to generate unique identifiers. > (Note to maintainers - %Z does not appear separately in the 5.93 > manpage.
