I need to run ntpd all the time and synchronise the clock when the
dialup connection is up. I really need a time server that doesn't need
peers but I will have to look into that later.

All the above script does is run '/usr/sbin/ntpdate -u pool.ntp.org
2>&1' to update the time. The rest is for debugging.
