Yes, I did make it work.

I wrote a short script called /usr/local/bin/timesync.sh as follows:


#!/bin/sh
(sleep 10; /usr/local/bin/ntpdate $@) &


and put the following in config.ini:

;@AC ;@EXEC /usr/local/bin/timesync.sh 10.70.x.x 10.70.x.x 10.70.x.x


where the x.x are replaced with the correct values for the time servers here.
If I was doing it again, I wouldn't hard-code the 10 in the script, but would make that the first command-line argument:


#!/bin/sh
#untested!
DELAY=$1
shift
(sleep $DELAY; exec /usr/local/bin/ntpdate $@) &
