The CMOS date is still right. When you boot into Windows, it will attempt to set the CMOS time to local time by syncing to time-servers out on the 'Net. When you boot back into FreeBSD, and you've got the system set up to use CMOS at UTC, you will see the time lurch. Your options are to set up FreeBSD to use CMOS at local time or to ntpdate-sync at startup to NTP servers on the 'Net. -- Jonathan Chen ---------------------------------------------------------------------- The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
