Hi

I have 3 new PCs on a small LAN and all use Windows XP I have found that the
clocks on all of them gain by about one and a half minutes every 2 hours.
Most PCs I have come across could never be called acurate time keeper but to
be out by this much is not good. Does anyone have any ideas?
 
are they dells. they have a time problem with available fix
from dell. or you need new batterys for your bios (don't
think so). and windows update has also put a little bug
into the clocks making the clocks want to be updated more
than normal.

This problem seems to happen quite often. Usually a steady rate of
loss/gain like 10 minutes in an hour. It appears to result from a
conflict with the BIOS over the interval between 'timer interrupts'.
Windows maintains the clock by counting these, so if the interval is not
the expected one, the rate is grossly out in this manner.

Try these steps:

1. Start->Run cmd.exe
2. net stop w32time
3. w32tm.exe /unregister
4. w32tm.exe /register
5. net start w32time

(note spellings w32tm and w32time in different commands)

Then use the Internet Time in Control Panel date and time to synchronise
the time regularly for a few days (preferably with the machine left
running 24 hours a day, though not necessarily on the net). That will
then check the residual rate and adjust the system's idea of time
between interrupts to give quite accurate time without the need to synch
very often
