Description: The difference in milliseconds between the time an event is triggered and January 1, 1970.

- #### version added: 1.2.6event.timeStamp

This property can be useful for profiling the performance of certain jQuery functions by getting the `event.timeStamp` value at two points in the code and noting the difference.

### Example:

#### Display the time since the click handler last executed.

    <!DOCTYPE html>
    <html>
    <head>
      <style>
    div { height: 100px; width: 300px; margin: 10px;
          background-color: #ffd; overflow: auto; }
    </style>
      <script src="http://code.jquery.com/jquery-1.7rc2.js"></script>
    </head>
    <body>

    <div>Click.</div>
    <script>
    var last, diff;
    $('div').click(function(event) {
      if ( last ) {
        diff = event.timeStamp - last
        $('div').append('time since last event: ' + diff + '<br/>');
      } else {
        $('div').append('Click again.<br/>');
      }
      last = event.timeStamp;
    });
    </script>

    </body>
    </html>
