[Tfug] PC Clock

[roger]

I just joined TFUG because I have two Linux machines running MythTV and 
know 0 about Linux. I currently have a concern about the system clock.
I've had a 10 minute drift forward in the past two months. Since I'm 
recording TV programs using the MythTV app, timing is critical. 

Anyone know of a utility that synch's the time to the atomic clock, 
similar to several Win apps?

Since either software or hardware is capable of some drift even if small 
why not run something like ntpdate anyway?
