Title: Setting Time
Post by: pisto on January 24, 2006, 03:01:30 am

Hello,
  last days I have had big problems trying to set date and time in my C1000. After searching the forums I found no working answer.
  Command "date" worked, command "hwclock" gave me an error related to "/dev/rtc" file impossible to open.
  but, if I tried changing time from Settings in matchbox, the system hung up!
  Later I have studied a little my configuration and I tried all these operations with "atd" daemon stoped. ALL worked again!
  So, my question, can this be true? Is there any solution for this, in order to automate the date-time changing from X-Windows?

Thanks!

That's correct - atd locks /dev/rtc (the hardware clock) while running, so you do have to stop it before setting the time.

The matchbox applets are mostly python - perhaps someone has the time to look through /usr/bin/datentime.py to see if some logic can be added to stop/start atd if/where required?

I ran into this problem recently (1.1.0beta1). How about modifying
/etc/apm/scripts.d/hwclock to read

suspend() {
  # first need to turn off atd for this to work
  /etc/rc.d/init.d/atd stop  
  hwclock --systohc
  return 0
}

resume() {
  hwclock --hctosys
  /etc/rc.d/init.d/atd start
  return 0
}


will this break anything else?

I doubt that would break anything - if you didn't want to see an error, you'd probably need to add something like:

Code: [Select]

# stop atd (but only if it's running)
if [ -n "$(ps | grep atd | grep -v grep)" ]; then
  /etc/rc.d/init.d/atd stop
fi
and

Code: [Select]

# start atd (but only if service installed and enabled)
if [ -x /etc/rc.d/init.d/atd ]; then
  /etc/rc.d/init.d/atd start
fi
