Events counting and timing.

Hi,

I’m building a program to count how many times I pressed the button and a timer that counts and displays the seconds (to 3 decimal places) between times that the button was pressed. So far, I was able to construct a simple VI to count the number of presses however, I’m struggling to Implement a timer that counts and displays the seconds between times the button was pressed. I would really appreciate any correction or feedback to point me in the right direction. My VI is attached.

Thanks in advance
