I'd imagine that could make a hell of a mess of building from makefiles.

If dates got out of order update by date, log by date, etc. would break 
and even if they stated in order you wouldn't be able to reliably say 
'checkout the repository from this date' because the commit dates would 
be essentially meaningless.

Theoretically in future once we have a more flexible system real file 
mod times could get stored separately from the commit times.  That would 
be quite a big change though (as others pointed out not all filesystems 
have concepts of creation and modification times).
