"move the UTC prime meridian" We'd have two prime meridians. One for time and another for longitude. (Not a deal breaker but we'd have to plan for it.)

- slavik81 2y agoWe have many prime meridians for longitude. The location of 0° on Earth is not the same in every datum. We also moved the traditional prime meridian by a hundred meters back in 1974 with the adoption of the IERS Reference Meridian.
- paulddraper 2y agoSaid another way, the prime meridian adjusted by (at max deviation) 0.1km 50 years ago and hasn't been changed since.* *Though on a small scale, tectonic movements fuzz the idea of "location" in general.
