Well, you experts tell me. I suspect that using the EXACT definition of
not the fictitious one, would allow a formula for the adjustment of time
for the next 100 years or so without appreciable variation. It would even
allow the computer to calculate what the leap seconds are, if they would
(apparently) stop messing with the system and leave it as a standard rule
based system. Without a table at all.
