Timeset -7 help!

[Anon]

How would I make this following code time, be set back -7 hours?

$filemod = filemtime($DOCUMENT_ROOT."/path/to/file.txt"); 
$filemodtime = date("F j Y h:i:s A", $filemod);

filemtime returns a unix timestamp, so you can simply subtract (7*3600) seconds from it before giving it to the date() function;
