Anyone who doubts the accuracy, legitimacy, etc. of pool services should
be able to purchase a GPS timing receiver and get the time from "the
horse's mouth". The investment required is about $100 US at a minimum.
Even less - US $34 now....
He did say a "timing receiver". That could mean a GPS receiver
specifically set up to supply time, including an on board temp
insensitive crystal to supply the time if the sattelite availability
goes to low.
There is no such thing as a "temp insensitive crystal"! A crystal can
be placed in a tiny temperature controlled oven to achieve the *effect*
of temperature insensitivity.
