I run chrony on my gateway.  It syncs with a bunch of time servers on
ppp-up, and runs continuously to keep track of the hardware clock drift.
I've also set it up to provide ntp services to my local network
(192.168.0.0/255.255.0.0).  Since my gateway is always on, my client
machines can just happily sync against it anytime they like, and since I
dialup at least once a day to collect mail, it all Just Works (tm).
