REJOICE! NO MORE LEAP SECONDS!
The Brief
- The description says the CGPM (BIPM) Resolution 5 would keep UTC free of leap seconds for centuries into the future, subject to Earth's rotation slowing too much.
- It links the CGPM Resolution 5 text and a BIPM livestream that discusses the decision in more detail.
- Chapters cover the timeline ("Gone by 2027"), off-by-one and time-smearing problems, and simpler time code.
Why watch · It explains a change to how UTC handles leap seconds, which affects software that computes or stores time.

Every second counts. And that'll be true for UTC from now until... at least centuries into the future! Assuming the Earth doesn't slow its roll *too* much.
