How can I match a clock time to a variable?

Hi there,
I am creating a GUI on matlab and want to output what is being clicked in real time. When a button is pressed on my GUI I out put a string variable 'Yes' or 'No'. I wish to be able to place the results of the button on a table. One column will have the button response 'Yes' or 'No' and the second column will have the time that the button was pressed.
For example
Response Time; Yes 1.30; No 5.13; Yes 9.48;
Is this possible? If so how would I go about it?

Do you want the time the button was pressed or when the callback was processed?

In the callback for the button being clicked, update the data on the uitable using,
TableData = get( handles.uitabletag, 'Data') % Fetch existing data
TableData = [ TableData; {'Yes',datestr(clock)} % update the data
set( handles.uitabletag, 'Data', TableData ) % upload updated data to the table

This will place the time the callback was executed in TableData, while often similar, this is not the time the button was pressed (nor released), but rather some indeterminate time after the button was pressed and MATLAB got around to processing the event queue.

I'm not sure, but it you change the callback to have "now" as the eventdata, it should execute when the callback is called. Whether or not that interrupts the event queue to take its value is I don't know.
