Steve Allen replied:
# GPS did choose TAI.
# For all practical purposes GPS = TAI - 19 s.
(GPS = TAI - 19) & (x != x - 19) => (GPS != TAI)
# For precise purposes it is important to recognize that GPS time varies
# from this -- recently by only plus or minus about 50 ns, but
# historically by more than that.

# This error alone taints all of the rest of the arguments in this note.
Um, I don't think you've shown that I made an error but, even if I
did, I hope most readers would consider each of the other arguments
on their own merits or otherwise.
