Simply put, how much physical distance on the globe/map affects a discernable change in time?- If I compute the zman for something, I do so based on (for some websites) my zip code. But that zip code covers a large area. Is it possible within a zip code to have more than one "time" when a zman starts or ends - even to the level of the second? Should a website that asks for latitude and longitude be asking for significant subdivisions to know EXACTLY where I stand? Does a degree/minute/second cover more than just my 4 amot?
- How many feet, yards or miles (or degrees/fractions of degrees) east/west becomes a measurable amount enough that it affects the computation of the zman.
- This leads to a question of whether people davening in a large area like a stadium might have a situation where a zman begins or ends for one extreme side, but that hasn't happened for the other side. I wonder what the halachic implications of that would be, but first, I have to understand the range of physical space we are talking about.

At what distance does a zman change?
Simply put, how much physical distance on the globe/map affects a discernable change in time? If I compute the zman for something, I do so based on (for some websites) my zip code.
