I've been experiencing a very annoying bug the last week or so. The time displayed in the clock in KDE does not keep time. It runs fast, gaining about 1 minute each hour.

I have the RTC module loaded at boot from rc.local to create /dev/rtc

For whatever reason, /etc/ntp/drift did not exist, so...

Reading the time directly from the hardware clock shows the 'correct' time. (It is exactly the same as the time displayed on KDE's clock on another computer running Slackware 12.1 and kernel 2.6.27.7, my wristwatch, and a clock radio.) Reading the hwclock reveals almost no deviation from those three other sources.

I also removed /etc/adjtime so ntp could recreate it, but still the displayed time keeps going fast. I'm really puzzled as to why this is occurring. Any suggestions?

I have not noticed it and just checked............mine is good to go.

I also have no drift file but I am using ntp.

Odd..........

After some trial and error and some testing, I found the fix to this. Hopefully this helps someone....

I was able to fix this by appending "clocksource=hpet" to the kernel's boot options.

Perhaps then by enabling HPET support in the BIOS the boot parameter might not be needed?
