add_time_to_title
(begin, end, metadata={})¶ Given a title and two times, adds the time info to the title. Example results:
"Number of Attempted Transfers (24 Hours from 4:45 12142006 to 5:56 12152006)"
There are two important pieces to the subtitle we add  the duration (i.e., ‘48 Hours’) and the time interval (i.e., 11:00 07022007 to 11:00 07042007).
We attempt to make the duration match the size of the span (for a bar graph, this would be the width of the individual bar) in order for it to make the most sense. The formatting of the time interval is based upon how much real time there is from the beginning to the end.
We made the distinction because some would want to show graphs representing 168 Hours, but needed the format to show the date as well as the time.
