[Comment 1 Andrew Roberts 2004-05-01 18:14:58 UTC]

You could try 'hwclock --debug --systohc', which might be helpful.
Have you got RTC support in your kernel?

[Comment 2 David Solbach 2004-05-02 02:47:02 UTC]

I activated these kernel-option:

<*> Enhanced Real Time Clock Support 

Now everything works fine. Guess it's no bug then. Thanks.


In case u need it, here's the Output before adding rtc-support:

root@bine init.d # hwclock --debug --systohc
hwclock from util-linux-2.12
hwclock: Open of /dev/rtc failed, errno=2: No such file or directory.
Using direct I/O instructions to ISA clock.
Last drift adjustment done at 1083457806 seconds after 1969
Last calibration done at 1083457806 seconds after 1969
Hardware clock is on UTC time
Assuming hardware clock is kept in UTC time.
Waiting for clock tick...
...got clock tick
Time read from Hardware Clock: 2004/05/02 09:22:21
Hw clock time : 2004/05/02 09:22:21 = 1083489741 seconds since 1969
Time elapsed since reference time has been 0.402402 seconds.
Delaying further to reach the next full second.
Setting Hardware Clock to 09:22:21 = 1083489741 seconds since 1969
Not adjusting drift factor because it has been less than a day since the last calibration.

Closing as FIXED as per comment #2. Thanks!
