Setting default Time Zone for DateTimes

Question

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?

Answer 1

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.
