The leap second stops soon. Experts in France decide this. A fixed world time starts on 20 May 2027. Before, an extra second happened sometimes.
Two kinds of time exist. Atomic clocks measure time very well. The earth turns uneven times. Both times do not match. The leap second fixes this before.
The new rule allows bigger gaps. The world time stays equal much longer. A change needs one full hour gap. This saves much work for time tests.
Computers have trouble with the leap second. They can crash during the shift. This harms power grids or traffic. Without changes, systems run safe.
The earth turns faster now. Experts fear a minus second. People must take one second away. Nobody tests this before. Tech can fail.
Normal people see no change. The sun stands a bit different. People do not note this. Only star experts or map experts look close.
