See 'man clock'.

If you are connected to the Internet, you can use a program like rdate or
ntpdate to update your system time from an accurate time server, like
time.nist.gov.  Then you can update your CMOS time with 'clock -w'.  A
simple script could be invoked with cron to periodically update the clock.
I have a call to such a script in /etc/ppp/ip-up to update my clock
whenever I connect to my ISP.
