Odd Session Behavior

[Asperon]

<?php
session_start();

if(!isset($_SESSION['time'])){
  $_SESSION['time'] = time();
}

echo $_SESSION['time'];

?>

For some reason, this code will resave time() in the $_SESSION['time']. It does not stay set
between refreshes. I was using date earlier, but realized that $_SESSION could not hold an
object so I started using time instead.

Also, later, at the end of the script I reset the $_SESSION['time'] based on the last saved data
entry in my MySQL table, which is also an integer, so it should still be set.

Any ideas?

P.S. Let me know if you need to see the whole script

Well, I figured it out, thanks again.
