<h1>OpenLayers Example</h1>
<p>WMS-T example: update the times, and the radar image will change. Uses Layer.mergeNewParams to update the date element with the strings from the input fields every time one of them is changed.</p>
<p>The inputs below describe a timestamp: The minute increments can only be updated in units of 5.</p>
<input size="4" type='text' id='year' value="2005" onchange="update_date()"/>-<input size="2" type="text" id="month" value="08" onchange="update_date()"/>-<input size="2" type="text" id="day" value="29" onchange="update_date()" />T<input type="text" size="2" id="hour" value="13" onchange="update_date()" />:<input type="text" size="2" id="minute" value="00" onchange="update_date()" />:00
