Subject: Time & Time Zones
Date: Sat, 12 Jul 1997 15:41:01 +0100
I don't know if it's of any use to anyone here, but after reviewing
previous conversations on the subject of time and time zones, especially
when considering that so many here are from different parts of the world
I have added a java based "clock" to my web site. The clock gives
current time based on GMT for several areas of the world, from London,
Moscow, Beijing, Bangkok, Seattle, Chicago, Tokyo, Sydney, Hawaii,
Washington, Mexico City, Cairo & Buenos Aires. Hopefully this may be of
use to someone here when checking times for concurrency in posts.

If any other time zone is required, let me know, and I'll add it to the
list.

I'm not sure on the variance of US based times, and have adjusted for
Pacific (Seattle) Central (Chicago) and Atlantic (Washington) time
zones. It my be that there is a greater variance in zones than this,
but that is about the best I could find.

It's available on http://www.shalako.demon.co.uk/index2.htm

Any comments, ideas or observations, as always are welcome. :)

For those without java capability, I can but apologise. It's kinda
difficult to do this in HTML alone <g>

The time zone thing is a good idea. Your biggest problem would be
daylight savings time. Pain in the ass. I've had to write code to
handle it. There are some states in the U.S. that don't use Daylight
savings. There are other states where it is county by county. Royal
pain in the ass. Israel's Daylight Savings starts on the last Tuesday
of a month (March, I think) whereas in the U.S. it always starts at
Midnight on a Sunday morning.

And in New Zealand we start/end Daylight saving time at 2:00 on a saturday
morning.

Great, thanks Brad, that makes me feel so much better </sarcasm> I knew
there'd be a catch to such a simple piece of coding... <g>

I couldn't actually find any information on the daylight saving of other
countries so I left it generalised on GMT, but then I must confess I
didn't look too hard. I'll see what I can find out, and if I can figure
out how, I'll add the code to alter the table accordingly. Maybe I'll
even get it right :)

In retrospect, it's possible that the time zones may appear wrong to non
UK viewrs, for the simple reason the zones are set up for GMT and
add/subtract sufficient totals to appear correct, viewing from teh
states may leave the coding wrong, though I could be wrong. If that is
the case, and Seattle viewers end up viewing the time incorrectly, ie. 8
hours before normal, I'm going to have some fun sorting that to read
from the system clock rather than actuall GMT. Hmmm... Maybe this clock
idea wasn't such a good one after all. Oh well, it's up there now, and
at least some people will find it useful :)

All of the time zone information is stored in the Registration Database
(registry) for Windows '95 and 'NT. I've got a bunch of code that does
all of the checking in a little clock application I wrote. I was
trying to learn it all. I hacked it. It was interesting, but a
pain. If you'd like to see some of it, I can show it to you. It's not
proprietary or anything.

That's why I get paid the big buck....yes...singular.

In my last message, I mentioned Israel because it came to mind.
Jaimie, there are SO MANY different ways of doing daylight savings.
Microsoft even split it up to handle the "last" X-day of a month by
storing it as the 5th X-day in a month. So, on the Israel side, it is
stored as the 5th Tuesday of March. By itself, that would mean that
once every 5 or so years they would have daylight savings because
normally March only has 4 Tuesdays. That took me a while to figure
out. **GRIN**

I'd like to put in my two cents that everyone would move to Arizona,
then we wouldn't have to deal with DST at all.

If you don't mind sending it through to me, I'd appreciate it, thanks.

Lucky fellow, I get paid zip. :)
