Problem 43666. Use a timetable to analyze a train timetable (Part 3)

Oh no, you missed your train to Boston (again?)! How many times can you miss that train today? (In other words, how many Boston trains depart on November 1, 2016?)

Example

DepTime = datetime(2016,11,1,[6 8 9],[22 51 05],0)';
ArrTime = datetime(2016,11,1,[9 10 12],[17 32 09],0)';
Destination = categorical({'BOS';'NYC';'BOS'});
tt = timetable(DepTime,Destination,ArrTime)
tt = 
       DepTime          Destination          ArrTime       
____________________    ___________    ____________________
01-Nov-2016 06:22:00    BOS            01-Nov-2016 09:17:00
01-Nov-2016 08:51:00    NYC            01-Nov-2016 10:32:00
01-Nov-2016 09:05:00    BOS            01-Nov-2016 12:09:00
