This is not a direct answer to the question you asked. :-) Is it impossible for you to a) run ntpdate at more regular intervals or b) use ntpd, also in the base system? Presumably you're talking about a frequently unconnected host using automatic ppp? If so, you could run ntpdate out of ppp.linkup. Alternatively, you could run ntpd and set up ppp's dial and active filters so that ntpd's synchronization attempts do not cause a dial attempt nor keep an existing connection alive. Ciao, Sheldon.
