title: Get unix timestamp in milliseconds with perl
body: <p>I understand we can use the <code>time()</code> function to get the <code>seconds</code> elapsed since the epoch. How do I get the <code>milliseconds</code> though?</p>
  
  <p>I'm doing an interop with a JavaScript based system where we deal with <code>milliseconds</code>.</p>
  
  <p>Thanks! Btw, I'm gonna be evaluating this script in the context of nginx.</p>
