Title: Add getTime.sh to boot
Post by: bmarkus on September 20, 2012, 05:14:18 AM

Due to lack of RTC system starts with LINUX Time Zero. Please add getTime.sh to boot process.

I don't think I can assume that the system would be connected to the internet.
In the most simple form adding:

until /usr/bin/getTime.sh; do
   sleep 3
done

to /opt/bootlocal.sh to run in background or
to cause the system to wait until time request is satisfied add to /opt/bootsync.sh

But perhaps would be safer to use a control loop counter around the getTiime.sh call.

Yes, you can't expect network will be available, best is running a loop in background with few tries only, starting after udhcpd invoked.

BTW, Raspbian is running ntpd in the background.

It helps to get system time. However time is updated when system is up and running, so you see files with Linux Time Zero in the base. Doesn't harm.

Anyhow, now I'm curious,  how is the getTime script initialized??   manually??  have never seen the time auto updated, maybe this is something I need to configure.?

Code: [Select]

root@fh:~# grep -r getTime /etc
/etc/etc/init.d/settime.sh: until /usr/bin/getTime.sh >/dev/null 2>&1
root@fh:~# grep -r settime.sh /etc
/etc/init.d/rcS: [ -z "$NORTC" ] || /etc/init.d/settime.sh &
/etc/init.d/tc-config: [ -z "$NORTC" ] || /etc/init.d/settime.sh &

Thank you Hiro,  I see settime.sh  calls  getTime.sh 

will have to investigate why my time is not updated

you might experience the same problem as me, that the server does not respond most of the time, and it is only tried once.

I just sync to my local ntp server with ntpclient.tcz instead.
