title: Remove the days in the timedelta object
body: <p>I have a column in a pandas <code>dataframe</code> that is created after subtracting two times. I now have a <code>timedelta</code> object like this <code>-1 days +02:45:00</code>. I just need to remove the -1 days and want it to be <code>02:45:00</code>. Is there a way to do this?</p>
