It's all rather parochial but it is the established terminology.
Doesn't Universal hint at the join of the SI second and Solar Time?
Interesting to see a commercial company using leap seconds as
a positive marketing play.

Could we rephrase that between geophysical and atomic timescales ?
Astronomers measure it and have to compensate for it, not cause it.

Good grief. MJD is used widely in astronomy, for example in variablility
