Returns the latest time of Kiddush Levana calculated as 15 days after the molad. This is the opinion brought down in the Shulchan Aruch (Orach Chaim 426). It should be noted that some opinions hold that the Rema who brings down the opinion of the Maharil's of calculating half way between molad and molad is of the opinion that the Mechaber agrees to his opinion. Also see the Aruch Hashulchan. For additional details on the subject, see Rabbi Dovid Heber's very detailed write-up in Siman Daled (chapter 4) of Shaarei Zmanim. If the time of sof zman Kiddush Levana occurs during the day (between the alos and tzais passed in as parameters), it returns the alos passed in. If a null alos or tzais are passed to this method, the non-daytime adjusted time will be returned.
