I enquired about internationalizing date/time strings in mail, particularly in mail headers. First, it was pointed out that RFC822 is no longer the final word; one must also consult RFC1123. In particular, RFC1123 says that the "military" time zones described in RFC822 are all wrong, and promotes the use of +/-HHMM time zone designations. This use of +/-HHMM was almost universally recommended by the respondents, even for North America. The time zone names (e.g. EST) are anything but unique. The traditional time zone name can be included on the date line as a comment, if desired (assuming it doesn't have any 8-bit characters). On the issue of Daylight Savings Time: as one respondent put it, using the +/-HHMM designations will "finesse" the DST issue. Of course, I should have realized this, since these don't describe your time zone in terms of location, but merely in terms of time difference from GMT. It does mean that at different times of year, your mail will have a different time zone designation (-0500 vs -0400, for example). Craig Everhart also said, about code to produce this kind of date string: > The code for this is freely available as part of the Andrew contribution > to the X.V11R4 tape, in .../andrew/overhead/mail/lib/arpadate.c . David Stone sent me more than I ever wanted to know about time zone names.

Would you mind mailing a copy of RFC1123 to me? I'm working on the mailer for my BBS, and it would be a great help. (I tried contacting you via e-mail, but I was unable to reach you.) -- Shawn P.

Send a message to SERVICE@NIC.DDN.MIL with a subject line saying HELP. It will tell you how to get individual RFCs, and the index. - Alan Millar
