instantiate a Date_HumanDiff object and run
$dh = new Date_HumanDiff();
echo $dh->get(time() - 5 * 60) . "\n";

get() accepts two parameters: The timestamp and the reference time. If the reference time is not provided, the current time is used. Both parameters may be unix timestamps, DateTime objects as well as strings that can be converted to a unix timestamp with strtotime.
The difference between timestamp and reference time is then converted into a human readable string.
