Relevant to those 1803 lunar distances by Lewis and Clark.
I can quite some relevant extracts from the 1803 Nautical Almanac that I
jotted down at my last library visit-
Astronomical times and dates, of course, starting at noon each day, 12
hours after the start of the civil day with the same name and date.

All times Greenwich Apparent time.

No doubt you're aware that EOT (Equation of Time) was then defined in the
opposite way than we do it now.
If there's anything else that anyone would find useful, I will note it down
at my next visit.
