Dear Fallible Fiend: Like Keiva, I doubt that polar tilt and the length of daylight is important for determining longitude.Sightings are done ideally at noon, and the time from noon to noon is twentyfour hours, regardless of latitude. Naturally, charts would be necessary, and distances found by spherical trigonometry.
At least that is what I believe. I promise to be cheerful if you prove me wrong.

As you well know, you and Keiva are correct. Thank you both for setting it straight. I didn't think it through. I was thinking (well, sort of) if one were at a known, fixed location in a non-tilted earth, one could use the constellations to tell the time. Even if this is true, the inference I drew would still be wrong.
Thanks,
k
