I find it a good idea to sync with a time server before running the 
hwclock command you suggest. 

The command to do that is rdate -s timeServerAddress

Information related to finding a public time server is available at

If you find your hardware clock drifting a inordinate amount it can be a 
good idea to put the above commands in a cron job.
