Trying to mount root from ufs:/dev/ada0p2 [rw]...
uhub0: 4 ports with 4 removable, self powered
warning: no time-of-day clock registered, system time will not be set accurately
msk0: link state changed to DOWN
However, I tried the following steps:
1) ran ntpdate to set the correct time
2) powered down
3) unplugged the network cable
and noticed that the real time is still correct.
Andy points out the time is taken from the fs shutdown in the absence of a RTC which is what I'm observing here.
