Whether UTC second can be 60
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 18 September 2026. No other catalogue keeps this.
Today is the operative word: we check Whether UTC second can be 60 every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
