Ah. PDP 11 running RT11 (the RT stands for real-time, you know, and it
was!). Bigger and much heavier than a breadbox it had a lot of power.
Oh, wait, I mean it *used* a lot of power. And you could modify it with

As I said, Windows is huge and evolving, and Sever is different from
regular Windows versions; be careful when mixing and matching versions.
Some of these technotes are pretty recent, like 2014 or 2015. See -

No, Julian days count days.
Those can be "days" in whatever time scale.
The astronomical almanacs had a longstanding set of tables expressed
in Julian Ephemeris Date (J.E.D.) which was a count of days of

There is no such connection. TAI times are

That's not correct. Both apparent and mean solar time are described
in seconds, and in both cases that's the angular second (1/86400
