Does the .Net DateTime contain information about time zone where it was created?
I have a library parsing DateTime from a format that has \"+zz\" at the end, and wh
No.
A developer is responsible for keeping track of time-zone information associated with a DateTime value via some external mechanism.
A quote from an excellent article here. A must read for every .Net developer.
So my advice is to write a little wrapper class that suits your needs.
