Return data with the timestamp

Hey, I`m doing a measurement and getting its data from (Keysight 34465A). The problem is that I don`t get the timestamp along with the data.I looked at the manual and found the command which should return the data with the time stamp but it doesn`t do so. Can it also be because of device? Please help if you have any ideas. Here is the piece of the code i use:

%code 
fprintf(key,'MMEMory:FORMat:READing:INFormation ON');             % command supposed to get data with timestamp
fprintf(key,'TRIGger:SOURce EXT');
fprintf(key,'TRIGger:DELay:AUTO OFF');
fprintf(key,'TRIGger:DELay MIN');
fprintf(key,'SAMP:COUN 100');
fprintf(key,'SAMPle:COUNt:PRETrigger 50');
fprintf(key,'TRIGger:COUNt 1');
fprintf(key,'INIT');
Readings=fopen('testreading.txt','w');
for jj=1:100
fprintf(key,'DATA:REM? 1');                                        % getting data
dat=fscanf(key);
dat=strread(dat,'%f','delimiter',',');
fprintf(Readings, '%f\t\r\n',dat);
end
fclose(Readings);
