Един набързо драснат плъгин за countdown

html частта може да изглежда по следния начин:
<div id="timerche" class="timer">
		<div class="timer2" style="height: 26px; overflow: hidden;">
			<div class="timer3" style="padding-left: 35px;">
				<div class="dash hours_dash">
					<span class="digit">0</span> <span class="digit">0</span>
				</div>
				<div class="dash">:</div>
				<div class="dash minutes_dash">
					<span class="digit">0</span> <span class="digit">0</span>
				</div>
				<div class="dash">:</div>
				<div class="dash seconds_dash">
					<span class="digit">0</span> <span class="digit">0</span>
				</div>
				<div class="klear"></div>
			</div>
		</div>
	</div>
а използването на плъгина да става така
var ts = 1345064399*1000; # timestamp * 1000
$('#timerche').countdwn({time_end:ts});
