Is there a way to set the time zone information to be unique for each Windows user? Like, a registry setting specific to that user.
For example, I want John to be CST and Mary to be PST. If John opens a program it says 5pm. If Mary opens a program it says 6pm.
Additional information: These users don't need to actually log in. I want to create two users, one for CST and one for PST, and use their credentials to run a program. The program will inherit their time zone settings and display the correct time.
More info: I plan on using these users in IIS for app pools so that different applications in the website can be run in different time zones and locales.
The only way Windows supports this is through Terminal Services, which won't help you. The time-zone settings are kept in the HKLM hive, and Terminal Services has a special setting that allows the Terminal Server to take a time-zone supplied by the incoming client-session and display that instead.
A better plan would be to use the timezone offsets in your code. StackOverflow is a better place to ask about that.
