Thanks for all the replies. I'm giving clockspeed a try. So far so good, but I'll only have definite results in a day or two. I'll post my findings. Anyway, I'll start looking for newer hardware and arrange a proper burial for this crappy and brave machine... --

OK, let me try this again: Old x86 desktop box (Pentium III @ 500MHz) running 5.0. Machine has been on 24/7 for the past few years (minus the occasional PSU replacement), serving mail and http under very light loads. Its local clock is drifting. A lot. Without ntpd running: # date; rdate -nv
