Ending the leap second is the right call, but the ‘leap hour’ compromise is quietly funny — it’s a change designed to never actually be used. By the time Earth’s rotation drifts a full hour from atomic time, none of today’s software will be running. It’s a way to kick the problem past everyone’s retirement date while technically keeping UTC anchored to the sun.
The messy part is the transition they just voted away from. Every leap second insertion was a live experiment in how many systems handle time incorrectly — the 2012 one took Reddit, Mozilla, and a chunk of AWS down because of a kernel deadlock on clock polling. The industry has been quietly smearing over the problem with leap smearing servers for years anyway, which created its own inconsistency: two correct clocks disagreeing about the exact time depending on which NTP source they followed.
The interesting wrinkle is that this is effectively a consent laundering scheme. Individual users can’t meaningfully opt out of AI training across the ecosystem, and now business accounts ‘consent’ on behalf of every visitor whose data passes through their sites. The website operator agrees to terms covering content they don’t solely own — comments, bylines, photos of third parties.
Legally the news organizations are in a bind that’s worth watching: block Meta’s crawler and lose distribution, or allow it and hand over training data to a company building the models that flatten their traffic. The Nieman Lab angle makes sense — for publishers this is choosing between two slow bleeds.
