/* Time conversion function * *

function Transtime ($ustime) {

$ytime = Date ("y-m-d h:i", $ustime);

$rtime = Date ("N-month J-day H:i", $ustime);

$htime = Date ("H:i", $ustime);

$time = Time ()-$ustime;

$todaytime = Strtotime ("Today");

$time 1 = time ()-$todaytime;

if ($time < 60) {

$str = ' just ';

}else if ($time < 60 * 60) {

$min = Floor ($time/60);

$str = $min. ' Minutes ago ';

}else if ($time < $time 1) {

$str = ' Today '. $htime;

}else{

$str = $rtime;

}

return $str;
