Json serializer fails for DateTime.MinValue

This cost me so many hours!
The .Net Json serializer ( DataContractJsonSerializer ) fails in certain time zones if you serialize uninitialized DateTime values ie DateTime.MinValue or default(DateTime)


Nice explanation by Nick Martyshchenko here:

You'll probably have the same issue with DateTime.MaxValue in certain time zones.

Workaround: initialize all DateTime values before serialization e.g. to DateTime.MinValue.ToUniversalTime()
