Many good posts here about what the problem might be, but in my 
experience, running ntp is often overkill for many simple hosts since it 
requires time to sync, measure the drift, etc...

The simplest solution by far is to drop a script in your 
/etc/cron.hourly folder, assuming a FC system, which contains something 
like:

#/bin/sh
/usr/sbin/ntpdate -u addressofntpserver.com

This will sync your time every hour, requires absolutely no daemon to be 
running and works very well.  If you want it to sync more often, say 
every 20 minutes, add an entry to your crontab.
