How to use ntp/ntpdate to fix my clock

[Patrick Dahiroc <patd@dahiroc.net>]

hi all

the time on my machine is seriously messed up - currently my machine is already on Feb 15, 2000.  digging through the package database i came across ntp and ntpdate and installed both (i have an always on connection to the net).  all i want to do i to keep the time on my machine correct.  so now i think i only need ntpdate when i try to run ntpdate it complains i need specify a server to ask. is there a list of machine that listens for ntpdate connection? where? do i need to get permission (something to do with auth stuff) to ask those machines for the time? 

thanks
