Setting hwclock --localtime fails

[Anders Ellenshøj Andersen <andersa@ellenshoej.dk>]

I run a dual boot system with Vista and Debian unstable.

The clock in Debian is two hours ahead because it thinks the time is UTC.

I have been adviced that I should use hwclock to set the time to local time, 
but I get this error:

kit:~# hwclock --localtime
select() to /dev/rtc to wait for clock tick timed out

Is there a bug? Any hints on what to do?

I have noticed that this error occurs during boot as well.

I think I also need to add that I have ntp installed.
