On my UNIX-PC (system software rel 3.51), the boot time displayed by who
is derived from the interrupt driven software clock.

After powering up the machine, the software clock is set to whatever time it
(would have) reported just before shutdown followed by power down.

If I simply reboot (without powering down and back up), It only looses about
20 or 30 seconds.
