I'll see if I can scare up a copy of ISO 8601. It's a shame so many standards docs are not open-access. There is only one point I want to further pursue. > I'm not convinced, because dates are not prose. A character sequence's status as prose is determined by context, not content. who am i is prose (if somewhat substandard English) in some contexts, and a Unix shell command in others. Or it might be part of an e. e. cummings poem. We cannot solve all of our man page formatting problems with sed, alas. Regards, Branden
