Here you are:-
Code:
<div id ="mylink" style="display:none" ><a href = "http://www.google.com">The link</a></div>
<script type = "text/javascript">
var now = new Date().getHours(); // current hour local time
if (now >=12 && now <=14) {
document.getElementById("mylink").style.display = "block";
}
</script>
But as remarked be aware that Javascript may not be available on all devices, or may be disabled. Also note that the times between which the link is displayed are referenced by the time as specified in the user's computer, that is local time.
