CentOS - Dec 2007 - Update repo rsync but no new repodata?

I just did a manual resync of my local update repo from  
mirrors.kernel.org/centos/5.1/updates/i386/

I got a new version of Thunderbird, but not a new set of files in the 
repodata directory.   Thus when I did a yum update against my local 
repo, I did not get the new version of Thunderbird.

I will note that the files on my local repo are dated Dec 20th and the 
ones on mirrors are dated Dec 21st.  The command I am using is:

#!/bin/sh
rsync -auv rsync://mirrors.kernel.org/centos/5.1/updates/i386/ \
--delete --exclude=debug/ /repos/centos/5.1/updates/i386

Oh, and the old version of Thunderbird was not deleted....

I confirm this.  The metadata files remained the same when a new
thunderbird file was added to the RPMS directory earlier today.

This has to do with the timezone.  You are seeing the UTC on the mirror.
