[CentOS] Updating hardware clock from cron

Is there a package to do this?
Normally the hardware clock is set during shutdown if one is running ntpd.
But if a long-running server shuts down unexpectedly, this isn't done, and
the hardware clock might be off by a lot when it comes back up. So setting
it periodically from a cron job could be useful.
What do others do? Adding a one liner to /etc/cron.daily that invokes
/etc/rc.d/init.d/ntpd would do it but it seems heavyweight to restart ntpd.
Alas, the script doesn't export just the sync_hwclock function.
