Question

Why am I getting two results when using these functions…

<?php
echo strtotime("2011-9-9")."<script type='text/javascript'>alert(Date.UTC(2011, 9, 9)/1000);</script>";
?>

this gives me 1315526400 and a js alert of 1318118400.. Why are these so different!?

Also, what is the best way to take a UTC timestamp (integer) and parse it for only the year, month, and day?

Thanks

Answer 1

Javascript zero indexes its months, so the PHP code refers to september, but JS refers to october.
From the Chrome dev console:

new Date(1315526400000)
Thu Sep 08 2011 20:00:00 GMT-0400 (EDT)
new Date(1318118400000)
Sat Oct 08 2011 20:00:00 GMT-0400 (EDT)
