I don't know much about C#, but on most platforms*, sleep() or its 
equivalent can be interrupted early.  It's not beyond the realms of 
possibility that this happens in C# too (e.g. your thread is stolen for 
garbage collection), and this might happen more often in a busier server 
environment.

Do you have some kind of loop to catch exceptions, and retry if you did't 
sleep the entire period?

* other platforms off the top of my head:
- *nixes can return from sleep early (e.g. after handling a signal)
- java can throw InterruptedException
- select(), etc.
