git-cvsimport bug with dates

Hi,

It appears that there's some kind of bug with git-cvsimport and dates.
 In a small repository I imported on Oct 24, I'm getting:

$ git log | grep ^Date | wc -l
957
$ git log | grep ^Date | tail
Date:   Tue Oct 29 21:10:17 2002 +0000
Date:   Tue Oct 29 17:41:05 2002 +0000
Date:   Tue Oct 29 00:43:27 2002 +0000
Date:   Mon Oct 28 23:36:40 2002 +0000
Date:   Mon Oct 21 21:35:57 2002 +0000
Date:   Fri Sep 20 22:18:01 2002 +0000
Date:   Mon Sep 16 20:05:27 2002 +0000
Date:   Wed Sep 11 21:14:03 2002 +0000
Date:   Tue Sep 10 16:37:16 2002 +0000
Date:   Fri Aug 23 16:03:22 2002 +0000
$ git diff @{2007-10-01}
warning: Log for '' only goes back to Wed, 24 Oct 2007 19:31:38 +0000.
fatal: bad object @{2007-10-01}

It appears that passing a date to git diff on any repository imported by git-cvsimport will show this error, as long as the date is prior to when the repository was imported.
