Hi all.
When I originally set up the machine which is now my server, it was a dual boot system. During slackware setup, one of the questions was if the clock is set to ut or local time. Obviously, I selected local time.
However, since this is now a gnu/linux only machine, I'd like to switch to gmt. What would have slackware configured differently if I told it that my hardware clock was set to ut?
More simply put, what else do I need to change besides my kernel config so that the system would know that the hardware clock is set to the universal time? Thanks in advance.
Greg

The way it works is that when you select UTC, Slackware writes a file in
/etc called localtime containing the word "UTC." It checks this on
startup and shutdown and invokes hwclock with a special flag to let it
know that it is set to UTC and makes it act appropriately. The easiest
way to switch back and forth, is to type "timeconfig" as root. This will
repeat the setting of your timezone and you can then pick UTC. You'll
still have to select a local time, but the clock should first be set to
UTC to get it to show up right.

Was curious, do you not then set the bios clock to UTC?

Hi, Scott.
You can either set the clock in the BIOS manually, or sync the time
automatically at boot-time via xnptd. This can either be done from a script
in /etc/init.d or you can even run it at regular intervals as a kron job.
Hope this helps.

Ah, thanks that would certainly do and as would rdate perform a similar
function. I think what I was wondering is if you were wanting to setup
your machine in UTC time, I was speculating on whether or not it would
be necessary to set the bios clock to UTC as the kernel would get its
initial time from here. True you could use rdate or a similiar program
to accomplish the same goal...hmmm

Yes, I used to do this for a machine that had a very inaccurate system
clock, I used the clock command in I think it was Slackware 3.3 or
something to set the hardware clock from the system clock at intervals,
and the system clock was updated from a time server everytime I dialed up
to the net.
Cheers.
