Re: impact on git of changing linux o/s system-date frequently

What are the implications of linux o/s system-date changes on git?

We plan on having test VM's on which the linux o/s system-date (linux "date" 
command) is changed several times to test time lapse scenarios, e.g. go 
forward 30 days in the future.  We use git to pull updates from the 
development machine to mirror repos and cloned repos on the test VM, and to 
create test areas (local repos) on the test VM.  We do not use git-push or 
git-commit on the test VM at this time.

Without making commits on the machine, there won't be any history being
created with misordered dates, so there shouldn't be any issues there.

The index should also be pretty resiliant to time warping as well, and
if you aren't modifying any of the git managed files, I don't think you
can provoke anything.

If you're doing edits of files, there's a slight possibility the edited
version could end up with the same ctime/mtime as the cache in the
index, and git would miss the change.  Again, it doesn't sound like you
are doing this.
