You can setup a your own NTP server following this howto: http://brainwreckedtech.wordpress.com/2008/08/25/howto-run-your-own-ntp-serv... and adapting it for CentOS, or you can use a workaround like trying to setup a cron job to run ntpdate every 15 minutes to sync system time with ntp.org public servers using unprivilleged port.
15 * * * * /usr/sbin/ntpdate -s -u -B pool.ntp.org
-s option tells ntpdate to print output to syslog; -u tells it to use unprivilleged port; -B tell it to adjust the time incrementally as oppose to instantly.
Then setup ntpd as a local ntp server for internal use. This ntpd uses it's localtime as the source instead of syncing from another ntp.org public server.
