[linux] Linux loopt achter

Ha Linux-vrinden,

To get more precise timing in a Linux system,
we changed HZ from 100 to 500 in the kernel (2.4.32) source file
This seemed to work perfectly.

Now, we face some problem that the (system)time is running behind
about 20 minutes a day.
(time difference between system clock and hardware clock, which is
operating accurately)
Probably this is a side effect of the above.
Are there perhaps other aspects we have to consider or adjust when changing HZ ?
Any suggestions for improvement are welcome.


With best regards,
Ad van den Broek
