get
A generic utility method for calculating any shaah zmanis (temporal hour) based zman with the day defined as the start and end of day (or night) and the number of shaahos zmaniyos passed to the method. This simplifies the code in other methods such as .getPlagHamincha and cuts down on code replication. As an example, passing sunrise and sunset or and sea level sunset (depending on the isUseElevation elevation setting) and 10.75 hours to this method will return plag mincha according to the opinion of the GRA.
Return
the Date of the time of zman with the shaahos zmaniyos (temporal hours) in the day offset from the start of day passed to this method. If the calculation can't be computed such as in the Arctic Circle where there is at least one day a year where the sun does not rise, and one where it does not set, a null will be returned. See detailed explanation on top of the [] documentation.
Parameters
the start of day for calculating the zman. This can be sunrise or any alos passed to this method.
the end of day for calculating the zman. This can be sunset or any tzais passed to this method.
the number of shaahos zmaniyos (temporal hours) to offset from the start of day
