panic: invalid bcd xxx

[Michael Gmelin]

Booting r313561[0] I get the following panic:

mountroot: waiting for device /dev/ufs/FreeBSD_install
panic: invalid bcd 177 (also 254, 255 etc.)
cpuid = 1
KDB: stack backtrace:
db_trace_self_wrapper...
vpanic()...
kassert_panic()...
atrtc_gettime()...
inittodr()...
vfs_mountroot()...
start_init()...
fork_exit()...
fork_trampoline()...
(copied from a screenshot, hence the ellipsis)

This is on an Acer C720 Chromebook, confirmed on two devices (one with
cyapa touchpad, one with elan touchpad). Same problem happened with a
CURRENT checked out about 10 hours ago. Previous versions of 12-CURRENT
worked ok (last version I tested personally was back in
November/December though).
