From what I can determine, these settings are stored in the registry.
The following two examples shows the differences when I changed from GMT to US Eastern Standard Time using the traditional Tim/Date Control Panel Applet and just accessed the "Time Zone" Drop-Down list:
BEFORE
------
[HKEY_LOCAL_MACHINE\System
"ActiveTimeBias"=hex:00,00
"StandardName"="GMT Standard Time"
"DaylightName"="GMT Daylight Time"
"Bias"=hex:00,00,00,00
"StandardBias"=hex:00,00,0
"DaylightBias"=hex:c4,ff,f
"StandardStart"=hex:00,00,
"DaylightStart"=hex:00,00,
"DaylightFlag"=hex:01,00,0
"ActiveTime"=hex:97,85,ff,
AFTER
-----
[HKEY_LOCAL_MACHINE\System
"ActiveTimeBias"=hex:2c,01
"StandardName"="US Eastern Standard Time"
"DaylightName"="US Eastern Daylight Time"
"Bias"=hex:2c,01,00,00
"StandardBias"=hex:00,00,0
"DaylightBias"=hex:c4,ff,f
"StandardStart"=hex:00,00,
"DaylightStart"=hex:00,00,
"DaylightFlag"=hex:01,00,0
"ActiveTime"=hex:97,85,ff,
Note: the following values were unaffected, but have been included for completeness:
"StandardBias"=
"DaylightBias"=
"DaylightFlag"=
"ActiveTime"=
The results do not require a restart, and I'm sure that they could be easily applied by running a .REG Script or using Remote Registry Server as an administrator.
What this DOESN'T DO is actually change the system time. I don't know of a way to do this other than from the Time?Date Control panel Applet or using DOS commands:
Echo 15.30.00 | Time
Echo 21/03/2006 | Date
or
TIME 15.30.00
DATE 21/03/2006
There is probably a Visual Basic or Windows Script that could change the Time Zone AND the system time elegantly and in one pass, but I'm not a programmer.
As far as tools to change the time zone, I don't know of any. The nearest Win98 gets is a tool to create your own custom time zones CD:\tools\reskit\config\tz

This is the location of the Time Zone information in the registry that's being used. All you have to do is change it. That's where the problem start.

Shows you how to edit the Time Zone information for each country and will show you where in the registry it is.. The trick is to get the information for your region in this area into the location of the Time Zone information that's being used.
