commit error: up-to-date check failed.

[Arcin Bozkurt]

Cvs commit aborts by saying
cvs server: up-to-date check failed for 'file'

The latest changes on the computer of the user who tried the commit were
- The time and date of the users machine was showing one day later, his 
time and date were corrected to point to the correct time (his machine's 
time was taken about 12hr before)

This shouldn't be a problem because cvs server is keeping all the info 
using the server's time/date, etc.

cvs update works properly but commit does give the error above.

What might be the reason of this error ?
