Server Time faster or slower than OS?

In the last few days our old mail server which is running Domino 8 started doing odd things with the dates and times. Mail which arrived at say 10:15am would show as arriving the previous day at 05:23am or some other random time. The amount of time the server was out from the OS date time was not consistent and would vary.

Having checked all the usual suspects such as regional settings, default user etc... I still could not find an obvious answer. Then by luck and a bit of cunning query writing I found a technote which described exactly what we were experiencing. Apparently the Domino server was suffering from "Time Creep", where there is some inconsistency on the OS ticks v the OS time and apparently was caused by a bug in the Domino Time package. This has been resolved in 8.02 and 8.5.

To resolve the issue there is a handy Notes.ini param you can set which tells Domino to sync the time with the OS:

SERVER_TIMESYNC_INTERVAL = 1 - every 5min (default)
SERVER_TIMESYNC_INTERVAL = 2 - every 1min
SERVER_TIMESYNC_INTERVAL = 3 - every 60min
SERVER_DISABLE_TIMESYNC=1 -disable polling

Having added this to the server it now appears to be correct but I will need to monitor it for a few days to be sure.

Here is a link to the full technote:
