Add time to a datetime array

I have to select the hourly value of relative air saturation and temperature at 14:05 a clock.

From an datetime array containing the 10 minutes values of all dates i created an daily datetime array using:

dt = table2array(T(:,3 ));                                           
dt = datetime(dt, 'InputFormat', 'dd-mmm-yyyy HH-MM-SS');
dt_daily = dt(1:144:end);

how can i add to each dt_daily 14 hours so that i have an index to extract the respective values from the table?

Thanks a lot for your help!

Best regards,

Arthur

I would use the datetime values you already have in your table T.

load T_matlab.mat
ind = timeofday(T.DateTime) == duration(14,05,0);

dayT = T(ind,["DateTime","H_air___","T_air_C_"])

dayT = 101x3 table
          DateTime          H_air___    T_air_C_
