swapped sign of longitude about astrotime HOT 2 OPEN

You are correct. The code was ported from a c++ version, which was ported from the original java at http://www.esrl.noaa.gov/gmd/grad/solcalc/sunrise.html. That website has a message "Back when this calculator was first created, we decided to use a non-standard definition of longitude and time zone, to make coordinate entry less awkward. So on this page, both longitude and time zone are defined as positive to the west, instead of the international standard of positive to the east of the Prime Meridian." I think I can make it conform to the standard definition of longitude by simply negating longitude at the top of calcSunsetUTC and calcSunriseUTC.

Any update on this?
