I have synced the time of my server to time.nist.gov. This server communicates with a client’s server which is also synced with time.nist.gov.
After noting that we seemed to be out of sync with the time server even after explicit syncing, I set up an hourly batch job to see if my hypothesis is correct and what is our time difference.
I set up the job on Friday and it has already checked the time 50 times. When I first checked on Friday,
w32tm utility showed a difference of less than 10 milliseconds. The last check, a couple of hours ago, shows a difference of 20 second.
There have also been 9 cases (in 50 attempts) of
error: 0x800705B4 which is a timeout error. The time difference seems to be increasing at the rate of 1 second every hours since Friday, 1/6/2012 5:35 PM EST
I have a Windows Server 2003 Enterprise Edition set up as a VMWare VM, the timezone is EST. Here’s my
DOS command that log the sync difference:
w32tm /stripchart /computer:time.nist.gov /samples:1 /dataonly >> D:\timedump.txt
Here are the last 4 entries:
