It appears to be correct when I look at at it, with complete day series and zeros in the second column, apparently for the missing days, and non-zero entries for the others.
In any event, if you have a data set with missing days, the way to fill them (with ‘TT’ being your original timetable) is:
TTr = retime(TT, 'daily', 'fillwithconstant','Constant',0);
This also creates a second timetable ‘TTr’ so the initial one is preserved.
