The OP ask for a command like Liunx's hwclock, to set up the RTC.

I for example on Linux do it like that:

$ cat /usr/local/bin/tool 
[snip]
        ntp)
            ntpdate ntp.favey.ch
            hwclock --set --date "$(date)";;
[snip]

FreeBSD sets the hardware clock whenever settimeofday() is called
(unless the sysctl machdep.disable_rtc_set is set). I don't think
there's a way to retrieve the current hardware clock settings from
userland.

Linux's adjtimex(2) is called ntp_adjtime(2) in FreeBSD." -
