[CentOS] Time is Fleeting: CentOS 4 question

I have recently built a new server using CentOS4.  I've found one major
oddity: time resolution is completely whacked.

I'm not using an external time source nor am I relying on NTP for time
resolution.  For some reason, time on this server moves forward at a far
more rapid rate.

Right now, all my other systems show Sunday May 8, 3:19 pm.  The CentOS
server thinks its Monday May 9, 3:54 pm.  I just reset it about four
hours ago to the correct time.

I'm using an inexpensive eMachines T6212 AMD Athon 64 processor and 1 GB
RAM.  

Can anyone suggest a reason why this server thinks it's 25 hours in the
future and growing more distant with each minute?

Thanks,
Bill
