Attach here small part your data as 'mat' file.
Reformat your data in timetable and use function retime.

How about the following?
% Read your text data file
T = readtable('test.txt');
% Create datetime vector
Time = datetime(T.year,T.month,T.day,T.hrs,T.mins,T.sec);
% Calculate daily counts
TT = timetable(Time,ones(size(Time)),'VariableNames',{'Count'});
TT = retime(TT,'daily','sum');
