Here is something that Google did not help with as quickly as I would have expected: how do I convert start and stop times into the time between events in seconds (or minutes)?

Or for the busy searcher “how do I convert Pandas Timedelta to seconds”?

The classy answer is:

start_time = df.interviewstarttime.map(pd.Timestamp)
end_time = df.interviewendtime.map(pd.Timestamp)

((end_time-start_time) / pd.Timedelta(minutes=1)).describe()

I found it hidden away here: http://www.datasciencebytes.com/bytes/2015/05/16/pandas-timedelta-histograms-unit-conversion-and-overflow-danger/
