Hello.  I just went on a trip to Europe, and I have a valid license of
Mathematica 5.0.  I changed the windows timezone to GMT+3hours.

Immediately Mathematica requested me to reenter the license, and then
it asked me to contact their servers for registrations.

Back in the U.S., with the old time zone, the program worked fine, and
did not request any registration, I only needed to enter the license
key and that's it.

I changed the time zone back to the original setting and everything
worked fine, Mathematica requested no registration and started up in
full working mode immediately.

Then I decided to play around with other time zones, and found that
Mathematica requested a reregistration in time zones from GMT+3hours
to GMT+8hours.  Otherwise it just started normally.

What the heck is going on, and why does Mathematica discriminate time
zones in such a way?
Any explanations would be helpful!
