title: PHP - what is diff between date_timestamp_get(date_create()) and time()?
body: <p>Both of those code are generate the same timestamp, so what their diff??</p>
  
  <p>Does it affect the speed of processing??</p>
  
  <pre><code>echo date_timestamp_get(date_create()); // e.g. 1478854173
  echo time(); // e.g. 1478854173
  </code></pre>
  
  <p>And does it depend on the local time of user? Or depends on the local time of server? </p>
