How to add datetime to a column in a table

I have a table that looks like this:

startTime endTime A B

________________ ________________ _________________ _____________

09-12-2019 21:00 09-12-2019 22:00 10 2

09-12-2019 22:00 09-12-2019 23:00 1 0

09-13-2019 01:00 09-13-2019 02:00 2 0

09-13-2019 05:00 09-13-2019 06:00 1 0

09-13-2019 13:00 09-13-2019 14:00 8 91

09-13-2019 14:00 09-13-2019 15:00 36 190

09-13-2019 15:00 09-13-2019 16:00 6 18

I want to populate it for every hour from the min to max start time

To generate these hours I used t3=min(Table.startTime); t4=max(Table.endTime); t_tot=t3:hours(1):t4

How can I add the missing hours to the table and have a value of 0 for A and B for these hours?

Is endTime for each entry always startTime + 1 hour ? If that is the case then you can create a timetable with startTime, A and B and then use retime to resample your time stamps to be hourly. I would suggest using a timetable instead of a table when working with time-stamped data as that would give you access to useful functions specific to time related data.

data = timetable(startTime,A,B);
hourlyData = retime(data,"hourly","fillwithconstant","Constant",0)

ans =

  19×2 timetable

         startTime          A      B

% If you need the endTimes you can add them after this
hourlyData.endTime = hourlyData.startTime + hours(1);
