Hi there Netlanders, Time for a little summary of the replies I got about timezones: Now I know all about timezones :-). I have discovered that there is no such thing as GMT time anymore. It has become Universal Time (UT) or Universal Coordinated Time (UCT) depending on who sent the reply. The appropriate references are ANSI Standard X3.51-1975 and ISO 4031, neither of which I have not got hold of (bit difficult out here) so I can't exactly say which of UT or UCT is the `correct' one. It turns out that Unix is backwards with respect to RFC822 (ANSI/ISO etc) time. Mail headers should have +nnnn if the sending site is East of Greenwich. The Unix timezone offset requires the offset to be -nnnn. All I need to do now is to hack about with smail to get it to shove the appropriate stuff on our mail headers, yeeHarr :->. See Y'all Later, and Thanx for the memories. ----- Praise the Employers for they do not know what I say but pay for the resources. ----- Bill D.

I think the new term for GMT is UTC - Universal Time Coordinated, not UCT. It is going to be incorporated in the new ISO C standard instead of the GMT.

Meteorologists still refer to GMT, though journal articles refer to it as UTC. == kwthomas ==

No longer does the British observatory at Greenwich the official source (the observatory was originally set up to deal with the problem of determining the correct longitude at sea). So, even though old habits die hard, "GMT" is not to be used. An acceptable name is also "Universal Time". "UTC" is, in English, "Coordinated Universal Time". All member nations of BIH coordinate their clocks with the official ones. Twice a year, someone has to take a portable clock from Fort Collins, Colorado, to Paris for comparison with the clocks there. BIH has no power except to issue recommendations on time, note, this includes leap seconds. Bob Devine ...!decwrl!cookie.dec.com!devine

The BIH, in english the International Bureau of Time is headquartered in Paris, France more than ten years ago changed the ordinary time standard from GMT to UTC, as well as some of technical specifications as to how it is calculated. There are several time standards, UTC, UT1 and UT2 and others depending on how they are measured. Lee -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- |Lee F.

Although GMT may not be "official" any more, I maintain that as
long as someone uses the expression, and other persons still
understand it, then the concept still exists.
Really! I still refer to our sports arena as `D.C. Stadium' rather than
`RFK', the Dept of Nukes as the `AEC', the `Motor Vehicle Administration'
as the `DMV', and my bank, now `Sovran', as it was originally, `Suburban
Trust' (Suburb Ant Rust:-). Oh, yeah, I almost forgot. I call my OS `UNIX'.
(Denmark went metric a *loooong* time ago, but you can still
buy butter by the pound here).
And we never got around to going metric, but that's how they sell liquor.
