将unix时间戳转换为twitter / facebook样式

Question

I'm trying to convert a unix time stamp to display like facebook and twitter. For example, when you see tweets or comments placed on twitter/facebook you see the date/time displayed like so:

'2 mins ago' or '2 days ago' or '2 weeks ago'

Does anyone one know of any function to get it working like this. I'm guessing it will be a custom one.

Any help is much appreciated

If you are using php you might want to try the following function which was posted by Matt Jones

// DISPLAYS COMMENT POST TIME AS "1 year, 1 week ago" or "5 minutes, 7 seconds ago", etc...
function time_ago($date,$granularity=2) {
    $date = strtotime($date);
    $difference = time() - $date;
    $periods = array('decade' => 315360000,
        'year' => 31536000,
        'month' => 2628000,
        'week' => 604800, 
        'day' => 86400,
        'hour' => 3600,
        'minute' => 60,
        'second' => 1);

    foreach ($periods as $key => $value) {
        if ($difference >= $value) {
            $time = floor($difference/$value);
            $difference %= $value;
            $retval .= ($retval ? ' ' : '').$time.' ';
            $retval .= (($time > 1) ? $key.'s' : $key);
            $granularity--;
        }
        if ($granularity == '0') { break; }
    }
    return ' posted '.$retval.' ago';      
}
