Daylight Savings Time
In my country DST is not observed. What the heck is DST and what is its implication on configuring Domino?
Thanks for your inputs!

FYI, DST is generally about 6.5 months of the year, and standard time is only 5.5 months of the year. A bit ironic, perhaps. In early April, when DST starts, sunrise averages a bit before 6, and sunset averages a bit after 6. By adjusting to DST, that becomes a bit before 7 to a bit after 7. It was first instituted in WWII, with the expectation that it would be easier to adjust shifts to end a bit later than to start a bit earlier, and this way, a shift ending as late as 7:00 would be able to work using natural light instead of electric, thus reducing energy needs. During the summer, shifts could be adjusted to end as late as 8:30 PM, or even 9:30 toward the edge of each time zone, all using natural light.

Qwaletee, nicely explained, as usual. I like the way you explain :) DST has been an area of fascination for me right from the beginning. I didn't quite understand it initially, more because in my country it is not observed.
Now lets take a look at this. An organization named ABC has ofices in New York (-11:30 Hrs?, DST), New Delhi (+5:30 Hrs, no DTS) and London (GMT, DST). How does this affect them, if it does. Is leaving them to "use the OS settings" all that is needed? What else if not?

New York is -5 hours, DST, by the way. (I'm in the next time zone over at -6.)

Oh yeah! You're right Barry. I miscalculated ;-) But then again, is that the standard time or when DST is in effect... lol

NY is -5:00 standard, or -4:00 DST.
UTC is a French acronym. In English, it would be UCT -- universal coordinated time. But the French acronym is the globally recognized one.
If you use a web browser to access Notes, then you are always usingteh server time, unless you use 6.x with the new $prefernces.nsf feature. Notes client will always adjust for both time zone and DST. In effect, with/without DST DEFINES your timezone. Just look at Windows TZ list -- Indiana has its own listing, separate from eastern Standard Time, because it has a different DST setting. The only "funky" things about a DST based TZ is that one day a year, there are two 1:00AM-2:00AM periods, and one day a year, there is no 1:00-2:00AM period. Also, users have to be used to dealing with schedling with someine in a different TZ... once you have the hang of that, the fact that DST applies or not shoudln't really throw users off more.
The main thing is to just get the settings right, let Notes take care of technical time translations after that, and be ready to provide users some basic understanding of what they are dealing with.
