        <h1>TimeSync test</h1>
        <p>
            This test uses the timesync extension to calculate a timeoffset with the server.
	    The time displayed below is the server time and should be the same for all clients no matter what their local clocks are set to. 
	    The accuracy should improve as each connect response is received.
