Although I am on 24x7, ntp can be used for dialup. These are the two lines I added. server 158.121.104.4 # timeserver.cs.umb.edu server 140.239.10.5 # ntp.ourconcord.net
However, you might just want to use ntpdate. ntp runs as a daemon where ntpdate is not. You can write a cron script that tests if you are online. If so, execute ntpdate (as root) to synchronize your clock. Or you could set up a script around your PPP program to execute ntpdate when you log on.
