Suppose you have to go back a zillion years. Now the fuzz on the period adds
to the fuzz on measuring an individual pulse.
Not to forget that pulsar frequencies spins down as the energy that they
emits is ultimately drawn from its rotational energy (PSR B1937+21 spins
down at 1.05 x 10^-19 seconds per second). In a zillion years this could
amount a bit of time (several hundred microseconds over the 2.29 x 10e8
years life of this pulsar if the spin down rate would have been constant
- too much drift for a real time-nut ;) )
