I don't know how portable %[ together with a maximum width is, because the
manual page for sscanf() doesn't mention "max width" for "%[", but it works
with Debian/GNU Linux Squeeze.

FYI:
But you must not break existing implementations (of any (closed-source) OS),
which depend on that behaviour of the RTC. Have a look at get_cmos_time() of
the Xen hypervisor for example (that is the one I have been looking at at the
an create lots of instances
from then, which have few changed relative to the master, so we don't want
the copying to happen there.
If haven't looked at QED yet, so thanks in advance for your answer.

Now to your problem: You should check the value
of /sys/devices/system/clocksource/clocksource0/current_clocksource in your

using "hwclock --hctosys --utc" re-synchronizes your guest clock to the host.
