Setting default Time Zone for DateTimes

I have an C# application that will be running in a different timezone than where I am developing it. It uses time-based data, and performs calculations and makes decisions based on the time-based data. I want to test using the real data, so was wondering how I could set the time zone or something similar of the application as if I was in the other timezone, and all variables of type DateTime would use this default time?

Is the DateTimeOffset class available to you? (it is not when you use the compact framework). Judging from its APIs, it seems to cover your requirements very well.

DateTime has only three "modes": DateTimeKind.Utc, DateTimeKind.Unspecified and DateTimeKind.Local. It doesn't make calculations based on the time zone. It doesn't offset it in any way. There is a DateTimeOffset that could help you (starting with .NET 2.0 SP2)

You would need to set the time zone of the computer that is running the application.

The easiest way would be to just change the timezone on your machine, which is getting picked up by the DateTime class. As a general recommendation I would do all time related calculations and storing of times in UTC, only for display purposes convert to the local time zone.
