44 No, it's not THAT much effort. You can get by with installing ntpd on a
45 single machine, pointing it at the upstream time server and pointing all
46 your clients to it. It's clearly recorded in the config file, you can't
47 go wrong.

49 It's understanding how this weird thing called time works that is the
50 issue. Take for example leap seconds..... urggggggggggg...
51
52 The basic question I suppose is why do you want to do it this way? What
53 do you feel you will gain by doing it yourself?
