$parsed=array();
$delta=(time()-1149986423)/(60);
$parsed[0]=round(($delta/(6024))-0.5);
$parsed[1]=round(($delta/60)-(0.5+$parsed[0]24));
$parsed[2]=round($delta-(0.5+($parsed[0]2460)+($parsed[1]*60)));
$grammar=array();
for($i=0;$i<3;$i++){
if ($parsed[$i] !== 1) {
$grammar[$i]="s";
} else {
$grammar[$i]="";
}
}
echo "Last online ".$parsed[0]." day".$grammar[0].", ".$parsed[1]." hour".$grammar[1].", and ".$parsed[2]." minute".$grammar[2]." ago";
