    Auto Update Time

Usage

var aut = new AutoUpdateTime(date, function(timeDiff) {
  console.log(timeDiff + ' ms passed since last callback'); 
});

// time goes by...

aut.clear() // clears the timeouts
Where date is anything that can be passed to new Date().
Intervals

Intervals vary with the supplied date.

less than 60 seconds ago: 1 seconds
less then 60 minutes ago: 30 seconds,
anything else: 15 minutes
