As you might already know, zmanim (for Shabbos, etc.) are determined by a number of factors, one being the elevation of the particular locale. But for some reason, if you check the charts and algorithms for the zmanim of New York (I'm thinking Monsey (elevation 548 feet), specifically), the elevation is not factored into the times. Any idea why this is? I know the difference would be nominal at best, but it's still a difference. We might as well use it, right? Any ideas why we don't?

Which algorithms are you looking at? – Daniel May 17 '13 at 14:17
These zmanim, for instance, do not include elevation: myzmanim.com/day.aspx?vars=US10952 – WhoKnows May 17 '13 at 15:26
This information comes from someone I know who wrote algorithms for Zmanim for Shul websites, and has nowhere seems to use elevation for these places. He was wondering why. – WhoKnows May 17 '13 at 15:26
@devir. It doesn't really answer your question, but if you open that myzmanim link and click on the picture of the mountains you can set the elevation. – Menachem May 17 '13 at 16:56
Thanks, yeah I saw that. But as you said, why not factor that in to begin with? – WhoKnows May 17 '13 at 18:15
