I think there is some misunderstanding here. I don't want to handle the
offset in the kernel, with one possible exception: when reading the
RTC for the first time to initialize xtime. Getting timestamps right as early
as possible might be important in some cases, and it's not a big deal
since the code to do this is small and thrown away anyway.

Oh and I can't remember whether the clock or hwclock command ever worked
on my machines. I think hwclock did once upon a time; life is so much
simpler with NTP anyway (but it is run quite late in the boot process,
actually just before the rc.local script on most of my machines and after
mounting NFS file systems and starting daemons like syslogd/crond/inetd).
