Are you proposing that the first day of September is the 0th? You might be able to do that with locale support and using strftime's %c option, but I'm not sure how powerful locales are (or how one even defines them).

If you just care about the format, check out the --date option in git-log's manpage. Especially the "format:" specifier, which relies on strftime, like:

  git log --date=format:'%A %Y-%m-%d %H:%M:%S (%z)'
