When I setup ntpd on my old 486 some time ago, someone on the list suggested adding some options to the kernel and recompiling. I don't understand what it does but it worked for me and my clock was way off. Here's a clip from the message: Another thing you can try is changing your clock source. Add the following lines to your kernel config file and recompile: options CLK_USE_I8254_CALIBRATION options CLK_USE_TSC_CALIBRATION That should calibrate two internal clocks against the CMOS clock, which is usually pretty accurate. Good Luck!
