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 test detects how "hwclock --systohc" untune the clock. Now the hwclock
command causes the hw clock to be wrong by 500ms each time it is reset.
The test resets the clock 10 times and result is 5 sec difference between NTP
and the clock. That's a bug... and it has to bee fixed in a next commit.

The cal command generates output that depends on time(). For reliable
regression tests we need to use still same time. It seems that LD_PRELOAD is
pretty simple way.

Now all code in util-linux uses sysconf(_SC_PAGESIZE) that is standardized and
preferred way of querying page size. The asm/page.h file is not included to the
code anymore. (This patch doesn't change mount's FS detection code which will
be removed later).

The col truncates output when multibyte errors is detected, but the problem is
not reported to stderr and return code is still same like for successful exit.
This stupid behaviour is fixed by this patch.

The patch adds tests/ directory with simple regression tests infrastructure.
Also, it adds the "ts-mount-paths" test that testing if all defined paths
(fstab, mtab, locks) are still same.
