Dennis Ferguson wondered:
I see Terrestrial Time being expressed as a Julian Date quite
a lot. What is the unit of that number if not Day?
We may refer to 86400 seconds in a time scale like TT as being its day
precisely because TT, TAI and other time scales were calibrated against the

In the appropriate contexts there are days of Terrestrial Time,
International Atomic Time, Barycentric Coordinate Time, Geocentric
Coordinate time, GPS system time, BeiDou system time, etc. Each of
those days is 86400 SI seconds in its own reference
