Was cpu scaling enabled on the old hardware by any chance?
eg: AMD Cool 'n' Quiet or Intel SpeedStep
Nearly every time I've had this happen it was the cpu scaling up and
down and the guest not handling the cpu clock cycle changes properly.
The time "jumping" is a symptom of this.
Disableing the feature in the host BIOS should fix that.
Another cause, I only saw this once, was the guest process "jumping"
from core to core every few seconds and the guest, again, not handling
it quite right.
I ended up having to manually assign cpu cores in the config files for
that box. :(

Is the clock on the host running fast? If it's not, then it can't be
"physically" running fast on the guest.

I will turn on the logging and let you know, I am really curious to see what is
changing that.
Am I wrong in thinking this is 2 issues.
1. The clock physically running fast. Independent of time sync
2. Time sync changing from external to Local CMOS when running a w32tm
/resync /rediscover commands.

So? Every time the source changes, something gets logged on 2008 and above. And
you can turn on logging for 2003. The change doesn't happen by itself.
I promise. :)

Well dang..If that doesn't beat all. Everytime I run the resync command the stupid
thing goes back to Local CMOS when I run a /query /source. So I set it again, run
the /query /source shows the time.windows.com<http://time.windows.com/>.
Run the update, restart services, run the resync..bam back to local cmos.
Its just my week for random MS issues...

Exactly the problem I've seen at two locations. That's why we moved away
from the hosts managing the clock for the guests.

We kept getting time issues when we had ESX set the time on Windows servers
because the domain will adjust the server time and then the ESX system adjust
it back. This kept causing the time to go back and forth and it turned out the
ESX systems were getting skewed from the NTP source at a greater rate. So let
the domain do its thing with the servers by setting time.

All domain machines. All VM guests sync to the ESX hosts. All workstations sync
to physical DC's that use standard Windows time service.

Are these domain machines? You don't sync them to a DC and sync the DC out to
an external NTP server?

As John notes, you should let the guests keep time for themselves, and not get
their time from the hosts.

We have a single VMware ESXi 4.1 running 1 Windows 2003 R2, and 1 x 2008 R2
server. The 2008 R2 server runs faster. Watching the clock it actually
tickets about 3 real seconds to 5 seconds on the clock in the console.
Needless to say this puts stuff out of sync pretty quick.
Looked online and I found a few posts regarding some weird time services, but
nothing Microsoft or VMware. Anyone seen this before? The 2003 Server runs
normally. I can resync against the DC and they are out of sync by 15 seconds
in under a minute.
