How would you go about snychronizing the clocks on a large number of QNX
systems? The only way I’ve found to change the time on a QNX box THAT
WORKS is through phlocale.

I’ve been using ntp4 without major problems, but never tried out
on large clusters.
It should also depend on what inter-node comm line you can use
(Ethernet? Serial? Parallel? SCSI? I2C? GPIO?)

We use a cron job to synchronize our development network (otherwise
‘make’ is always unhappy about the file dates 
). Here’s my script,
executed once in an hour:
#!/bin/sh
SERVER=qnx6-server
if [ X$HOSTNAME = X$SERVER ] ; then
exit 0
fi
if test -d /net/$SERVER ; then
echo “Synchronizing local time …”
TZ=UTC /sbin/rtc net $SERVER
TZ=$(cat /etc/TIMEZONE) /sbin/rtc -s hw
date
else
echo “Synchronizing local time … failed: No server found!”
fi
