There are a number of different date formats used around libgs ephem.Date, datetime, pandas.Timestamp to mention some. Also modified Julian time and various string formats.

Time formats that can be converted:

datetime	python `datetime.datetime` class
pandas	`pandas.Timestamp` class
ephem	`ephem.Date` class

Parameters:	to (str) – One of the abovementioned formats float_t (str) – If converting from a numeric, specify one if it is ‘julian’ or ‘unix’, can be omitted if converting from other formats ignore_ambig_types – Only allow conversions to non-ambigous types (i.e. none of the numeric or string formats)
