Yes, but we won't need 100ns precision for those historical dates.
Historically, calendars came to be from observing the movement of planets and stars. Now:

Neither of which makes sense without having a common reference point (start of Gregorian calendar being one such possible reference point). Trivial example: there is exactly one day between 1582-10-04 (Julian c.) and 1582-10-15 (Gregorian c.), i.e., different reference points.

Yes, and I bet they're hyper-aware about the calendar system(s) they're using. The rest of our mortals can just use Gregorian calendar :)

Surely they'd be using some kind of timestamp standard not a UUID?
That is not the only sense in which we care about dates. For example, we might want to talk about which of two events came first, and by how much. Historians have lots of uses for dates before the introduction of the Gregorian calendar.
