fixed
A method that returns the local time for fixed chatzos. This time is noon and midnight adjusted from standard time to account for the local latitude. The 360 of the globe divided by 24 calculates to 15 per hour with 4 minutes per degree, so at a longitude of 0 , 15, 30 etc... Chatzos is at exactly 12:00 noon. This is the time of chatzos according to the Aruch Hashulchan in Orach Chaim 233:14 and Rabbi Moshe Feinstein in Igros Moshe Orach Chaim 1:24 and 2:20. Lakewood, N.J., with a longitude of -74.2094, is 0.7906 away from the closest multiple of 15 at -75. This is multiplied by 4 to yield 3 minutes and 10 seconds for a chatzos of 11:56:50. This method is not tied to the theoretical 15 timezones, but will adjust to the actual timezone and Daylight saving time.
