It's not obvious why a new system is needed. UTC, TAI, or unix-time are sufficient.
The primary defect I see in the SIT proposal is that it isn't obviously based on the SI, but rather tied to the Earth. Defining a new unit that is 86.4 seconds long feels troublesome for everyone.

- kybernetikos 4y agoYeah, I played around with a decimal time: https://kybernetikos.github.io/UIT/ https://kybernetikos.github.io/UIT/ but eventually realised that my seconds, minutes and hour equivalents were just names for some of the decimal places of the Julian day number.
- shadowofneptune 4y agoI don't see what makes the second less tied to the Earth than the day. The SI system is for scientific purposes, it doesn't have units important for civil purposes like liters. If you were to completely redefine civil timekeeping (good luck!), the day feels like a better unit to focus on.
