When I run NTP on it, the = freq goes straight to 500.0 (over a period of a few days) and stays = there, while the offset grows and grows. I recently switched this machine from Debian Linux to FreeBSD (wanting = to learn more about FreeBSD). Under Linux, I used adjtimex to modify = the TICK value and (once I had converged on the right value) NTP was = able to stabilize the clock. Is there an equivalent hack for FreeBSD? Thanks! Rick=
