rdate and ntp are two different animals. rdate requests a 32 bit answer from the server. These 32 bits contain the current date of the server in unix format (number of seconds since 01/01/70). The clock of the client machine is then set to this date, with no compensation for network lag, skipping any cron jobs that would have been run between the old time and the new one. ntp will set up communication between the server and the client where the clock of the client machine will speed up or slow down so as to match the clock of the server machine (after compensation for any network lag). This means that no cron jobs will be skipped and no significient lag will occur.
