The offset that git maintaines is basically always ignored by git except 
for pure printout purposes.

For example, when you traverse commits, git normally picks the next 
reachable commit to show by using the date. The UTC offset has no effect 
on anything.

In fact, when we parse a commit, we don't even *parse* the timezone info. 
Look in commit.c: parse_commit_date. The timezone really doesn't even 
exist as far as any "real" git operation is concerned. It's just saved 
away, and it's _shown_ in "git log", but it has no real meaning apart from 

So git very much only works on UTC time internally, and the only thing 
that actually matters in a string like "1234567890 -0700" is the first 
part. The "-0700" is _literally_ just a comment that is only ever even 
parsed by "pretty_print_commit()".

Btw, CVS doesn't have any TZ info at all, so CVS also internally always 
saves in UTC. It then tends to print out logs in whatever timezone you 
happen to be in at the time of printout, afaik.
