Build an epoch 1 of 2 ways: Using seconds past a Julian date: # Epoch('ET', sec=1e8, jd=2451545) or using a matplotlib day number # Epoch('ET', daynum=730119.5) = ERROR CONDITIONS - If the input units are not in the allowed list, an error is thrown. = INPUT VARIABLES - frame The frame of the epoch. Must be 'ET' or 'UTC' - sec The number of seconds past the input JD. - jd The Julian date of the epoch. - daynum The matplotlib day number of the epoch. - dt A python datetime instance.
