{% codeblock datetime/gmstrftime.js lang:js https://raw.github.com/kvz/phpjs/master/functions/datetime/gmstrftime.js raw on github %}
function gmstrftime (format, timestamp) {
  // From: http://phpjs.org/functions
  // +   original by: Brett Zamir (http://brett-zamir.me)
  // +   input by: Alex
  // +   bugfixed by: Brett Zamir (http://brett-zamir.me)
  // -    depends on: strftime
  // *     example 1: gmstrftime("%A", 1062462400);
  // *     returns 1: 'Tuesday'
  var dt = ((typeof timestamp === 'undefined') ? new Date() : // Not provided
  (typeof timestamp === 'object') ? new Date(timestamp) : // Javascript Date()
  new Date(timestamp * 1000) // UNIX timestamp (auto-convert to int)
  );
  timestamp = Date.parse(dt.toUTCString().slice(0, -4)) / 1000;
  return this.strftime(format, timestamp);

Please note that php.js uses JavaScript objects as substitutes for PHP arrays, they are 
the closest match to this hashtable-like data structure. 

Please also note that php.js offers community built functions and goes by the 
[McDonald's Theory](https://medium.com/what-i-learned-building/9216e1c9da7d). We'll put online 
functions that are far from perfect, in the hopes to spark better contributions. 
Do you have one? Then please just:

This code
{% codeblock lang:js example %}
gmstrftime("%A", 1062462400);

{% endcodeblock %}
