Step 5 setInterval sample misfiring

[mitchellporter]

Just ran a quick test using Step 5 listed on the github.io page: https://bunkat.github.io/later/

I made some small tweaks to the code from the sample when testing setInterval:

  // will fire every 1 minute
  var textSched = later.parse.text('every 1 min');

  // execute logTime for each successive occurrence of the text schedule
  var timer2 = later.setInterval(logTime, textSched);

  // function to execute
  function logTime() {
    console.log(new Date());
  }

It fired correctly the first time, but on the second interval it fired logTime() 3 times in a row, right away.
