The references I have read suggest to me that ISO 8601 takes YYYY-MM-DD to be a 24-hour period, and YYYY-MM-DDT00:00:00 to be the second at the start of the day. > Exactly.

Or to the start of the week(or month or year, etc.) and use <that date>/P1W (or P1M or P1Y, etc.). What about a user who desired no datestamp at all? Would they just use something like 1970-01-01T00:00:00/P68Y? What about time zones? Lets say person A, signing the document, has a local time offset of GMT+2 and person B, receiving the document, has a local time offset of GMT+1. Person A has their app set to round down to the beginning of the day, which in person B's local time is 23:00:00 on the previous day. I guess person A seeing 20110618T000000/P1D and person B seeing 20110617T230000/P1D is a non-issue, since the two refer to the same time interval in UTC. - -- Best regards MFPA mailto:expires2...@ymail.com Pain is inevitable, but misery is optional. -----BEGIN PGP SIGNATURE----- iQE7BAEBCgClBQJN/MwAnhSAAAAAAEAAVXNpZ25pbmdfa2V5X0lEIHNpZ25pbmdf a2V5X0ZpbmdlcnByaW50IEAgIE1hc3Rlcl9rZXlfRmluZ2VycHJpbnQgQThBOTBC OEVBRDBDNkU2OSBCQTIzOUI0NjgxRjFFRjk1MThFNkJENDY0NDdFQ0EwMyBAIEJB MjM5QjQ2ODFGMUVGOTUxOEU2QkQ0NjQ0N0VDQTAzAAoJEKipC46tDG5poxcD/A3h hbgAqMlilzqIbTPoBLUIkdhG09tAcixQfgJTIvSIue/WY0VoZ3Z5KoDZ4znIYkK5 5gbhFN0/F753LJ+TAec+8+BjD3z0r4htqvblQPyh/8KbTZ3Mrv6kM/xnN07f/seT EFtbiNStHPPWPE8mcMUqFDLoLQbBmVA4GFc2959B =tn5l -----END PGP SIGNATURE----- _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
