79. What we have to do, therefore, to determine the second correction for sunset is to find the difference between the day of the solar year under consideration and 185 days, and take the correction for tropical longitude for the day so arrived at. If the solar year we are considering exceeds 185 days, the sign of the tropical longitude for the difference will remain unchanged : otherwise the sign should be reversed. This correction should then be added to the equation of time in order to determine the interval between sunset and 6 p.m. local time, while the total so arrived at should be added again to correction (1) adverted to in sec. 63, *i.e.*, the correction for terrestrial longitude, in order to arrive at the interval between 6 p.m. *Lankâ* time and *local* sunset.
