CentOS likes to store the hardware system clock in GMT time. Windows
likes to store it in the local time zone. The multi-hour switch is an
artifact of dual booting with this disparity in play. If either system
updates the hardware clock while running, the other OS will get thrown
off by several hours.
The fastest way to 'resync' the clock is using the ntpdate utiltity. It
is part of the 'ntp' package. As root run: 'yum install ntp'. You can
then reset the clock in CentOS by running 'ntpdate' as root.
