when the sun is directly over head, directly above an open well, and the light shines down into the exact bottom of the well onto the surface of the water, is it 12 noon?
According to my little almanac program, doomsday. Here transit never happens higher than 67° 46'. And that's at 12:29 pm local. Actually between time zones which are irregular and daylight savings which are political and bizarre to calculate, time can be very confusing to figure. Writing that almanac program had me cross-eyed more than a few times. (Find local time given UTC and lat/lon)

So, what time do you want it to be?
lol.

Not unless you are in Greenwich.

Don't think so, Greenwitch latitude is about 51.48° and the Earth's precession is about 23.5°. Let's check: US Naval Observatory says altitude at transit is 66.6°

Who need a watch? just stepped into the Wayback machine and I'm on time.

the only real difference between a good tracker and a bad tracker, is observation. all the same data is present for both. The rest, is understanding what you're seeing.

i just hate it when the sun touches the bottom of the well, and the Dragons begin to emerge and climb the walls of the well. but just as soon as they begin, the sun moves on, the light shifts, and the Dragons re-submerge.
back in the day, i worked with a lady who never wore, nor owned a watch. she didn't know what they were good for.
Be careful there, depends on the size of the well. The Sun moves 15° per hour so you hafta do the trig. Sorta like Eratosthenes. Pretty clever for about 240 BC.
