My time is going off all the time since a few weeks. Not sure when it
started, but I now need to do a netdate every 4 hours and the time
difference is between 1 or 2 seconds up to 5 minutes.
Anybody an idea what might be causing this?

I had a similar problem. What fixed it was to set the BIOS clock to a
slightly different time, boot Linux. Reboot and set the BIOS to the
proper time and then use the time feature in OpenSuse to set it to the
same time. I don't know why that fixed the problem.
Will try that.
If your clock is slow, you might change the backup battery on the
motherboard.
The PC is not turned off, so the battery could not be there, for all I
care.

Depending upon the motherboard the battery may run the clock all the time
and is continually recharged. But if old enough it takes less and less a
charge. Since the charging circuit take a few milli or nanoseconds to
recharge the depleting battery you will loose that time. The effect is
cumulative so eventually the clock will loose more and more time.
On other motherboards the battery only comes into play when the computer
loses power or gets below a certain level. Some boards I have seen use the
battery in brownout situations where there is enough power to keep all your
lights on and the computer on, but it strains the computer to run under
those conditions. Sometimes the clock will lose some time. Brown out
situations are far more harmful to computers than power surges. You might
not notice the effect except with some older monitors the whites suddenly
become less white.
It might be your battery but it might also be software.
