Hmm, this may explain something that I have been observing on
Windows+cygwin. When I run `git diff`, I sometimes get it reporting
that all (from what I can tell) files have changed, like a `find .
-type f -exec touch {} \;` command was run.

I was going to report this on a new thread, but this looks like a more
relevant place to do so.

My Windows machine is currently in Daylight Savings Time mode, and
from my observations, I have only seen this repeat first thing the
next day. I am not sure why, but every 24hrs, it looks as if the file
time reported by and checked from git is different to that reported by
stat.

I have not had time yet to play around with the mingw port and this
new stat implementation to see if it addresses this issue.
