In my case, it complained and prevented sudo from running.

That didn't work.  I believe that is used to reset when it will ask for 
a password.

I believe that if you set the clock back more than a certain amount of 
time, in my case, it was something like 3 hours (I don't recall 
exactly), sudo will simply not work.

Rebooting the machine fixed it, but that's really a microsoft solution. 
  I've added a password for root, so now I can use either sudo or full 
su, depending on what I'm doing, which is much more convenient.
