we want to be able to jump the clock arbitrarily.

Another problem remains:  How do you deal with leap seconds?  I mean,
given that 1 minute is not always 60 seconds, then what time was it
XXXXX seconds ago?   Maybe some kind of lookup table is necessary, but
in such case, isn't it a better choice just to use the
clock_settime/settimeofday syscall?
