 This timeline uses a segmentSize of FIFTEEN_MIN_SEGMENT_SIZE. The segment group
 is defined as 28 included segments (9:00 AM through 4:00 PM) and 68 excluded
 segments (4:00 PM through 9:00 AM the next day).

 In order to exclude Saturdays and Sundays it uses a baseTimeline that only
 includes Monday through Friday days.

 The <code>startTime</code> of the resulting timeline will be 9:00 AM after
 the startTime of the baseTimeline. This will correspond to 9:00 AM of the
