I need to write a code to record time stamps each time mouse is clicked. The following code works but only for 13 iteration or 13 presses. Is there a simpler way to do so?

for i = 1:length('ButtonDownFcn')
waitforbuttonpress
tt(i) = now;
end

length('ButtonDownFcn') asks for the length of the string 'ButtonDownFcn' which happens to be 13 characters.
How many presses would you like recorded, and how would you like the user to indicate that they want to stop clicking?

S.hFig = figure('menu','none',...
'pos',[400 400 320 50]);
S.th = uicontrol('Style','text','Position',[10 10 300 30],...
'String','Hit Space Bar to record Time Stamp');
timestamp = [];
set(S.hFig,'KeyPressFcn', @(~,~) assignin('base', 'timestamp(end+1)', now));
Caution: this will only work as a script, not within a function.
There is no specific way to stop: clicks will be recorded as long as the user cares to make them. You can access the timestamp variable any time after it is initialized. The user is not given any method to indicate that they want to stop, or that any further action should be taken, because that is a feature you have indicated you do not require.
