Determine The Input Time with tic,toc

Hello, I want to elapse the time that user spend on entering input. How can i do that ? I tried this below but MATLAB gave like 3.6175e-05 seconds. It looks really short. Here is my code

tic;
 userinput = get(hObject,'String');
 ts=toc;
 disp(ts);
 a = 5;
 
 timeratio = ts/a ; 
 set(handles.text12,'String',num2str(timeratio,'%.0f'));
 disp(timeratio);

Perhaps you should look at the third party Psychtoolbox

I assume that hObject is a uicontrol object of style edit.

Your current script reads the elapse time of getting the current string-value of the edit box. That time is not affected by the users interaction with the edit box.

User interaction with the edit box object invokes various callbacks (if set up properly). I assume that it is possible to let one callback run tic and another toc. The callbacks are well documented, see Callbacks for Specific Components as a starting point.
