I have. The users who end up with the most problems are laptop users.
I wonder if windows basically does a forced 'get my time right from
sources' when it awakes as I rarely had issues with AD/windows boxes
on it... but other OS's have that problem. I believe that SSL will
also have problems in some use cases if the clocks are too off.. but
that might have been Kerb related also.
