title: Effective method for Date.parse in javascript
body: <p>In a method, i am using Date.parse to convert the date to millisecond as below.</p>
  
  <pre><code> Date.parse(Tue Apr 1 00:00:00 PST 1930);
  </code></pre>
  
  <p>but i am using it for 1000 points , so the execution time for Date.parse is 60ms(shown in profiler), i need to optimize it, is there any other way to do it or Date.parse is the only way?</p>
  
  <p>Thanks in advance</p>
