Here are some things you can do with Gists in GistBox.
// Use Gists to store code you would like to remember later on
console.log(window); // log the "window" object to the console

This table shows the modifications that needs to be done in parse_time to return Time objects instead of Datetime objects

First importing import astropy.time as t

Input instances for time_string Current working of parse_time Proposed changes to return astropy.Time
astropy.Time return time_string.datetime return time_string
now return datetime.utcnow() return t.Time.now()
pandas.Timeseries return time_string.to_pydatetime() return t.Time(time_string)
isinstance(time_string, pandas.Series) and 'datetime64' in str(time_string.dtype) return np.array([dt.to_pydatetime() for dt in time_string]) return np.array([t.Time(dt) for dt in time_string])
datetime return time_string return t.Time(time_string)
tuple return datetime(*time_string) if time = (2018,10,3,10,43,5,6) see code here
