If you are connecting to the internet, you can use a program 
called ntpd:

Name       : ntp
Arch       : i386
Version    : 4.2.2p1
Release    : 9.el5.centos.2.1
Size       : 2.4 M
Repo       : installed
Summary    : Synchronizes system time using the Network Time 
Protocol (NTP).
URL        : http://www.ntp.org
License    : distributable
Description: The Network Time Protocol (NTP) is used to 
synchronize a
            : computer's time with another reference time 
source. The ntp
            : package contains utilities and daemons that 
will synchronize
            : your computer's time to Coordinated Universal 
Time (UTC) via
            : the NTP protocol and NTP servers. The ntp 
package includes
            : ntpdate (a program for retrieving the date and 
time from remote
            : machines via a network) and ntpd (a daemon 
which continuously
            : adjusts system time).
            : Install the ntp package if you need tools for 
keeping your
            : system's time synchronized via the NTP
