No. ntpd slows down the correction but the time continues to drift more and more. I started ntpd with the "-s" flag at my last reboot. When I sent my mail: uptime: 19:27 real time: ~17:30 machine's time: 18:49 =>gap: 01:19 Now: uptime: 20:33 real time: 18:29 machine's time: 20:23 =>gap: 01:54 > > Dave > >>dmesg: >> >>console is /pci@1e,600000/isa@7/serial@0,3f8 >>Copyright (c) 1982, 1986, 1989, 1991, 1993 >> The Regents of the University of California.
