Colleagues, What's the command to update the CMOS clock to the time of the kernel clock? ntpd does a good job of keeping the accurate time in the kernel clock, but from my experience, this time is not propagated to the CMOS clock which lives its own life. As a result, there is a large time skew everytime the box is rebooted, which prevents from Kerberos login until the kernel clock is synchronized. In other words, what's the FreeBSD equivalent of the Linux "hwclock --systohc" command? And no, contrary to popular belief, the correction of the CMOS clock does not happen automatically in FreeBSD even if ntpd is running. If there is a way to display the time of the CMOS (RTC) clock, I would be interested to know too. TIA. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN sip:sudakov@sibptus.tomsk.ru
