The unix timestamp is a number representing the number of seconds since 1970. Most applications use this value to keep track of what time it is. If you have a unix timestamp and need to see what time it represents, you can create a basic php script to decode it for you. Create a time.php in your public_html foler, and enter the following data:
<html>
<body onLoad="document.form.time.focus();">
<?
if (isset($_GET['time']))
{
echo date("r", $_GET['time']);
echo "<br><br>";
}
?>
<form action=time.php method=GET name=form>
Timestamp: <input type=text name=time> <input type=submit>
</form>
</body>
</html>
Then view it through the web, enter the number and submit the form.
