gmt option in kernel

gmt option in kernel

[Gregory Nowak]

Hi all.

I was pretty sure that there was a config option when doing make config where you had to answer "y" to something about the hardware clock being set to gmt. However, I've gone through the config twice, and can't find it. My kernel is 2.4.19.

Was this perhaps in the 2.2.x kernels, or am I simply imagining things?
Thanks to Adam for the info about timeconfig.
Greg

Hi.  It's in the power management section.

That explains it. I'm running acpi now, so no wunder. Thanks.

Greg,
That's an install time option, its not a kernel configuration.
You'll probably find you have a tzconfig utility for setting up your timezone information.

Hmmm, no, that option's in the Slackware set up, if you go into the set up
utility and go down to the configure your system option, it's in there.

No it is the hwclock program that is called from your  rc
scripts that sets the system clock; here is how it works:
When you boot the system; the kernel clock is unset. You run
hwclock
or hwclock -u
if your hardware clock keeps gmt. this sets the kernel's clock to the
cmos clock.
After this point; typing date will yield the right date.
gettimeofday and other clock functions should return correct local time.
As the machine shuts down; an rc.. script
runs hwclock -u -w
or hwclock -w if the time is localtime in the hardware clock.
If the kernel is told that the time source is synchronized by ntpd
or similar; it will write the time value back to the cmos clock every 11 minutes
which is optimal for a room temperature quartz oscillator or so they tell me.
You can tinker with this using adjtimex and friends.

Regards, Kerry.
