The One-Second War

  • Article

Why leap seconds exist, their benefits and problems, and the upcoming decision if they should be abolished or kept (or a 3rd option).

Personally I'm in the "Kill It" camp. Theoretically they're relevant, but pragmatically they're not, and the only ones who truly care about them have already moved on to other time systems. Time zones already muck up the solar-position-vs-time-of-day issue, so it's not like leap seconds make it worse (or better).
