</li>

##Preview

class Dashing.Countdown extends Dashing.Widget
ready: ->
setInterval(@startCountdown, 500)
startCountdown: =>
current_timestamp = Math.round(new Date().getTime()/1000)
end_timestamp = Math.round( Date.parse($(@node).find(".more-info").html())/1000 )
seconds_until_end = end_timestamp - current_timestamp
if seconds_until_end < 3600
$(@node).parent().remove()
else if seconds_until_end < 0
@set('timeleft', "TIME UP!")
for i in [0..100] by 1
$(@node).fadeTo('fast', 0).fadeTo('fast', 1.0)
else
d = Math.floor(seconds_until_end/86400)
h = Math.floor((seconds_until_end-(d*86400))/3600)
m = Math.floor((seconds_until_end-(d*86400)-(h*3600))/60)
s = seconds_until_end-(d*86400)-(h*3600)-(m*60)
if d >0
dayname = 'day'
if d > 1
dayname = 'days'
@set('timeleft', d + " "+dayname+" " + @formatTime(h) + ":" + @formatTime(m) + ":" + @formatTime(s))
