If you compile --with-audit the hwclock tool reports changes in sys/hw clock to
audit system. The real long-term and final solution is probably add hooks for
/dev/rtc to kernel, but it's not implemented yet.

quote from rh150493:
The kernel code, when setting the BIOS clock notes that the clock time
ticks to the next second 0.5 seconds after adjusting it (see
linux/arch/i386/kernel/time.c).
hwclock --systohc sets the CMOS clock at the 1 second boundry and thus
causes the clock to be wrong by 500ms each time it is reset. If the
clock is set every shutdown then the clock will have a reboot-count
related drift as well as the natural drift problems of the clock. Note
that this also mucks up the drift calculations, of course.

The patch to allow "hwclock --rtc /dev/rtc1" and so on,
since "/dev/rtc" may not be there and "/dev/rtc0" may not be
the right answer either.
The "--rtc" is compatible with next Bryan Henderson's hwclock
versions.

This patch add all missing headers, man pages and README files to automake
stuff and "make dist-gzip" produces useful tarball now.

The generated autotools stuff shouldn't be maintained by SCM. After check out
from git use ./autogen.sh. For more details see README.devel.
