Updating and displaying CMOS clock

What's the command to update the CMOS clock to the time of the kernel
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.
