<?php
echo $_SERVER['HTTP_USER_AGENT'] . "\n\n";
$browser = get_browser(null, true);
print_r($browser);
?>
There are other parameters in $_SERVER super global variable that you might find helpful as well such as time info. check for that here
GetDate() for getting date
<?php
$today = getdate(); <---- In correct (updated below)
print_r($today);
?>

You cannot get browser time from PHP because PHP runs on the server. It knows nothing about client and is completely ignorant of client time. But you can use JavaScript inside PHP and hack the browser time, like this
echo "<script type=\\"text/javascript\\">";
echo "localtime = new Date();";
echo "document.location.href="https://stackoverflow.com/questions/10247038/$PHP_SELF?client_time=" + localtime.getTime();";
echo "</script>";
