I checked and the cron job usually adjusts the clock by about 0.2 to 0.3 sec every hour. Sure thats probably more than ntpd would adjust it in any one iteration were ntpd running ...
according to: http://www.eecis.udel.edu/~mills/ntp/html/ntpdate.html
its not too kooky or dangerous to use ntpdate + cron rather than ntpd; 0.5 sec is given as a cutoff for it being less disruptive when making clock adjustments.
Its interesting to hear what other folks are doing. I had assumed folks normally don't run ntpd on each and every server and that ntpdate + cron was much preferred; maybe I am off-base.
ntpdate can set my clock backwards. ntpd, after you've first run it, won't. If you're using this to combine logs between machines you may not appreciate an hourly backwards step in time. :) adrian -- Adrian Chadd I'm only a fanboy if <adrian@creative.net.au> I emailed Wesley Crusher.
