Whats the long view problems with leap hours instead of leap seconds?

Me too!. With todays computerised economy. Are you sure all financial
systems handle transactions during a leap second event correctly. 30
years ago this was no problem. A human would not be tricked, but the
computer program must take explicit care of all corner cases.
If the astronomers want UT1, maybe they should lobby to get UT1-UTC or
UT1-TAI broadcasted on the data channels of GPS or Galileo. Even if
its a prediction, it would be much better than the current implicit
btw, TAI (and UTC) is a weighted sum of many clocks around the
world. How much does the autors of the proposal contribute to the
timescale? If the biggest "time factories" in the world make a
suggestion, maybe you read it twice...?
