Twitter Date Format

twitterDateFormat.js

// This formats dates like how Twitter does on their tweets I originally wrote
// this because I did not want to add an external dependency (such as moment) to
// my project for something so insignificant (date format). I couldn't have
// easily generated it on the server side since the dates are relative to the
// end user's browser's timezone (and I specifically wrote this to run on the
// client).
//
// Usage: twitterDateFormat(time)
// time can be anything JS' Date can understand

var twitterDateFormat = (function() {
  var months = [
    "Jan",
    "Feb",
    "Mar",
    "Apr",
    "May",
    "Jun",
    "Jul",
    "Aug",
    "Sep",
    "Oct",
    "Nov",
    "Dec"
  ]

  return function(time) {
    d = new Date(time);
    return (d.getHours() % 12 || 12) + ':' + String("00" + d.getMinutes()).slice(-2) + ' ' + (d.getHours() < 12 ? 'AM' : 'PM') + ' - ' + d.getDate() + ' ' + months[d.getMonth()] + ' ' + d.getFullYear();
  }
})()





/**

Testing:

I wrote a little test for this. It only outputs and rerquires a human to verify the tests' outcome

var d = new Date()
for (var i = 0; i < 49; i++) {
  var d = new Date(d.getTime() + 1800000);
  console.log(twitterDateFormat(d))
}
