I wonder what the effect of using a time based access list on udp123 once a
week would be on the NTP algorithm?

Hello Julie,
yeah, that4s what it sounds like - but it would be quite a pitty if
you have to poll ntp servers over an ISDN dialup line which would be
almost a leased line then. I wonder why it should not be possible to
change the interval like you can do it in several unix and windows
apps :-(
