A much more reliable way to check is
rpm -qa --last |less
or simply run
yum update
and see what it thinks needs updated yet.
If things are reasonably up-to-date I would expect the --last list to
have a tzdata-2011b package listed near the top.
One other thing the --last list will revel is WHEN the updates were
applied, if they consistently are at a particular time of the morning
then it may be based on a cron job.
