Hi,
the following actually is Part II of the thread
"Where is timezone (Red Hat 6.2)"
that I started Oct 28.
(Redhat 6.2, Kernel 2.2.14-5.0)
I want to set my Hardware clock *and* the System Time (= Linux Time) at
system-start with 2 commands, back-to-back, in /etc/rc.d/rc.sysinit ... my
main question: will I ruin my system with it (the most important part of
this message is at the very end in the lines starting with >>>> ... the
rest of this mail: just comment, to be as verbose as possible.
-------------------
hwclock --debug --adjust -utc # this will set the HW clock according to
# the drift factor hwclock found out with
# my glorious help ... the most important
# option: --adjust .. the rest just for
# security, 'tho not being completely
# sure whether it makes sense for a
# system start script.
hwclock --debug --hctosys # sets the System Time from the before
# correctly adjusted HW clock - most
# important (seemingly): --hctosys. As
# for the other option: same comment as
# for the 'adjust' stuff above
-------------------
the boot script that sets my clocks currently seems to be
/etc/rc.d/rc.sysinit, the corresponding date/time setting part seems to be
this one (my comments after 4 >>>>, the rest of it (save newly added
spaces) as it was written by Red Hat or whoever it was):
############################################
# Set the system clock.
ARC=0
SRM=0
UTC=0
if [ -f /etc/sysconfig/clock ]; then
. /etc/sysconfig/clock
# convert old style clock config to new values
if [ "${CLOCKMODE}" = "GMT" ]; then
UTC=true
elif [ "${CLOCKMODE}" = "ARC" ]; then
ARC=true
fi
fi
CLOCKDEF=""
CLOCKFLAGS="--hctosys"
case "$UTC" in
yes|true)
CLOCKFLAGS="$CLOCKFLAGS -u";
CLOCKDEF="$CLOCKDEF (utc)";
;;
esac
case "$ARC" in
yes|true)
CLOCKFLAGS="$CLOCKFLAGS -A";
CLOCKDEF="$CLOCKDEF (arc)";

CLOCKDEF="$CLOCKDEF (srm)";
;;
esac

/sbin/hwclock $CLOCKFLAGS
>>>> and replace it with the one following line:
>>>> hwclock --debug --adjust -utc; hwclock --debug --hctosys
action "Setting clock $CLOCKDEF: `date`" date
>>>> Danger?? I'd like to simply test the stuff and see what happens
>>>> but I thought (new as I still am to Linux) to get some advise before
>>>> I ruin my system ..... :)

Thanks in anticipation
