Clock drift issues

[Alex]

 Hi Guys,

 Running 8.2-RELEASE/amd64 as the operating system on my VPS.

 Every couple of weeks I am finding myself having to log in and resync 
 the clock as it's drifted (I am in Au (GMT+10)).


 Today again:

 ----------------------------

 srv# date
 Mon May 30 14:21:16 EST 2011

 srv# /etc/rc.d/ntpdate start
 Setting date via ntp.
 30 May 14:37:41 ntpdate[8207]: step time server 203.171.85.237 offset 
 958.736122 sec

 srv# date
 Mon May 30 14:37:43 EST 2011

 -----------------------------


 Is there any fix for this?

 Thanks, Alex.
