CVS timestamping question

[mshardogg]

Hi:

I am working with a bunch of people on a project and using a cvs
repository. We are located all over the world and were wondering how
cvs does timestamping to ensure we are always working with the latest
version. Does it always use GMT? Is our timezone differences something
we should be concerned about or do we not need to worry about it? We
will all be using the the unix version of cvs. 

Thanks,
