I'm researching a bit of a problem maintaining time synchronization between systems. I finally decided to measure the actual clock variance between hosts, and found that over the course of 13 hours, there was a rather large (IMO) drift. Relative to the 'main' host:
- systemA gained 3 seconds
- systemB gained 2 seconds
- systemC lost 7 seconds
Is this a relatively normal scenario? The 'main' system and systemA are brand new HP DL380's, while systems B and C are 2-3 years old.
We're going to check the CMOS batteries, but I don't know if that affects how the clock runs while the system is powered on.
