A JavaScript equivalent of PHP's time_sleep_until

{% codeblock misc/time_sleep_until.js lang:js https://raw.github.com/kvz/phpjs/master/functions/misc/time_sleep_until.js raw on github %}
function time_sleep_until (timestamp) {
  // From: http://phpjs.org/functions
  // +   original by: Brett Zamir (http://brett-zamir.me)
  // %          note: For study purposes. Current implementation could lock up the user's browser.
  // %          note: Expects a timestamp in seconds, so DO NOT pass in a JavaScript timestamp which are in milliseconds (e.g., new Date()) or otherwise the function will lock up the browser 1000 times longer than probably intended.
  // %          note: Consider using setTimeout() instead.
  // *     example 1: time_sleep_until(1233146501) // delays until the time indicated by the given timestamp is reached
  // *     returns 1: true
  while (new Date() < timestamp * 1000) {}
  return true;

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:
