If timezones might be a problem area, than it might be worth while to see it in the context of the actual application. For local, one user only, use, the problem will be practically non-existent. Multiple users across multiple machines will make it more difficult since you need a verified source for each users timezone. But then again what about travellers, wrongly set-up machines (right time wrong zone, wrong time right zone and wrong zone with wrong time?) or people who just prefer to do have their time set to UTC regardless of their location and season (when I travelled alot, I just set my wristwatch, phone and laptop to UTC). -- MPH http://blog.dcuktec.com 'If consumed, best digested with added seasoning to own preference.' -- http://mail.python.org/mailman/listinfo/python-list

It is a field in the header of every message. Show the full header, and look for the field named ‘Message-ID’. Ideally the value of that field is unique for all messages ever, but there's no technical enforcement of that so it wouldn't serve to *guarantee* unique identification. It's good enough to use as an identifier in referring people to read messages, though. -- \ “Oh, I realize it's a penny here and a penny there, but look at | `\ me: I've worked myself up from nothing to a state of extreme | _o__) poverty.” —Groucho Marx | Ben Finney -- http://mail.python.org/mailman/listinfo/python-list

How would I find the message ID? In Thunderbird (the newsreader that you're using) there's a little '+' to the left of the message subject line. That shows the headers. You can alternatively use [View - Message Source], or keyboard [Ctrl U]. From that you find that the message id is hifkh3$br...@news.eternal-september.org Then, kicking and cajoling your web browser to turn in the direction of Google Groups' Usenet archive, groups.google.com you click the Advanced search button, paste the message id, and find that Google is unable to find your article, he he. It's common, it's a very very unreliable archive. However, as with most things, the Great Wall of Google prevents you from reporting this. There's no known way to report any bug to Google. As with Microsoft in the old days (reportedly Microsoft employees weren't even allowed to use the words bug or error with customers, only, at worst, problems), there are Google web forms and whatnot, but they all end up in cul-de-sacs, so that, together with the total impossibility of reaching any human at Google, one very very strongly suspects that it's Google *policy* to never admit to bugs, or waste time on fixing them. And so, I suspect, Google Earth still places Norway in the middle of Sweden, and I know for a fact that Google Groups still actively removes the space at the end of a valid signature delimiter, and Google Talk acts up in various ways, and so on: quite serious bugs, but no way to report them (thousands upon thousands have tried, at one time a movement was founded with its own web site, but the Great Wall of Google lets no-one through). And considering this, and the fact that Google's archive is now the main Usenet archive, message id's are not that useful, really. So asking for a Usenet article's message id is just showing off -- that one is not up-to-date on current technology (it gets more unreliable year by year).
