Calculate sunrise and sunset times for a latitude, longitude and date.
Solar noon shifts by four minutes per degree of longitude within a time zone, which is why sunset differs by an hour across a wide zone. Sunrise and sunset are then symmetric about it. Being at the western edge of a time zone means noticeably later sunrises and sunsets than the eastern edge, on the same clock.
