Summary
The General Conference on Weights and Measures passed Resolution 5, ending UTC leap seconds from May 20, 2027, ahead of the 2035 date set in 2022. UTC stays 37 seconds ahead of TAI and may drift up to an hour from Earth-rotation time. Engineers avoid an untested negative leap second and can eventually drop leap-second handling code. One open issue is that WWV's DUT1 broadcast assumes an offset under one second. The post's 30% negative-leap-second estimate and the 2035 comparison could not be verified.
