Last Modified Script With TimeZone

[jimmygle]

I am having problems with this script I made to convert the last modified date to my pacific timezone.

Here's the code:

// Specified time zone offset from web server.  For my website,
// I am located on the west coast of the United States, and the
// server is located on the east coast of the United States.  So
// the offset is -3 for me.  But you must know the time zone of 
// your web server.
	$houroffset = "-3";

// Converts the hour offset so it is compatible with the PHP date
// statement.  *** Nothing to be edited here ***
	$timeadjust = ($houroffset * 60 * 60);

// Function for getting the last modified date and changing it to
// your time zone, and then printing it.
	function last_modified($page_url)
	{
	// Gets the filename from the function.  This filename must be
	// Specified in the function though, or it **will not work!**
		$filename = filemtime("/home/path/to/script".$page_url);

// Refer to [url]www.php.net/date[/url] for formatting the look of
// your date display.  The current format(l, F j Y g:i:s A) will
// display as June 30 2005 11:41 AM
// Converts the last modified file date into a readable time	
	$modified_date = date("F j Y g:i A", $filename);
	$modified_date = date("F j Y g:i A", $modified_date);
// Converts the readable time into specified time zone.
	$modified_date = date("F j Y g:i A",time() + $timeadjust);

// Prints the modified date in your specified time zone
	print $modified_date;
}

The server is located on the east coast, and when I wrote this script it wasnt the same. I originally intended this script to be just a current time script with time zones, but then I modified it to do this... But it isn't working. I would appreciate some help here.

Thanks in advance.

EDIT: Sorry about wrong section. Can someone please move it.

The function doesn't know what "$timeadjust" is, because it's not in the function's scope.

Doing it something like this will make the function more flexible and reusable:

function last_modified($page_url, $offset = 0) 
{ 
    $filetime = strtotime('+' . $offset . ' hours', filemtime($page_url)); 
    $modified_date = date("F j Y g:i A", $filetime); 
    return $modified_date; 
}

// For server time:
echo last_modified('./test.php') . '<br />';

// For your time:
$houroffset = -3; 
echo last_modified('./test.php', $houroffset);
