--- Comment #1 from Conrad Meyer <cem at freebsd.org> ---
How are you setting the date and reading the date?

FreeBSD does use 64-bit for time_t on amd64, but cannot control the hardware
clock's range.  Given you observe the correct date prior to reboot, I think
we're probably doing the right thing in the OS.

I believe the lost range after reboot is due to a limitation of your PC
hardware's clock (atrtc(4)), which uses two digits of binary-coded decimal for
the year; years wrap at exactly 100 years, which is what you observed.
