The leap second is dead. Long live the leap hour.
From here on, clocks will not be adjusted by +-1 second every ~1.5 years, when UTC time differs from astronomical time, due to changes in Earth's rotation time.
Clocks will now be adjusted when the discrepancy reaches one hour, which won't occur for thousands of years.
We will let future generations (robots?) deal with the headache of adjusting clocks without crashing their computers.
