here is a tutorial on time and getting the last modification

<?php
echo "This file was last updated on ";
echo date('l d F Y, \a\t H:i:s T', getlastmod());
echo ". ";
?>

<?php
$file = "time2.php";
echo "The file $file was last updated on ";
echo date('l d F Y, \a\t H:i:s T', filemtime("./$file"));
echo ". ";

?>

And here is the final tutorial for the day on time

<?php
$file = 'time3.php';
$data = stat($file);
$accessed = $data['atime'];
$modified = $data['mtime'];
$created = $data['ctime'];

echo "The file $file was...
\n";
echo "last accessed" . date('l d f Y, \a\t H:i:d', $accessed) . ",
\n";
echo "last modified " . date('l d F Y, \a\t H:i:s', $modified) . ",
\n";
echo "and created" . date('l d F Y, \a\t H:i:s', $created) . ". ";
