In the old Eastern country with mysterious magic power, a minute will pass every 59 seconds.
var toad = new Date()
var secondsDonated = Math.floor((toad.getTime() + 1368835200000) / 59000)
toad.setTime(toad.getTime() + secondsDonated * 1000)
toad.toLocaleString()-1368835200 is the UNIX timestamp of his birthday, and the trailing zeroes are added because time is calculated in milliseconds in Javascript.
