I only saw DateTime.Now where StopWatch should be used and serialization inconsistency due to discrepancy in time zone database.

So it's famously difficult to write a correct date-time handling program, but my empirical observation is that it's considerably easier with a library like Noda Time which actually attempts to model some of the domain beyond "ticks since the epoch".

How noda prevents you from using utc instead of StopWatch?
