php - Time ago function accuracy -

i have function in gets date post , supposed write how long ago posted. when use function says posted 43 years , 4 months ago odd reason.

function relativetime($date,$precision=2) { $times=array(365*24*60*60   => "year",             30*24*60*60     => "month",             7*24*60*60      => "week",             24*60*60        => "day",             60*60           => "hour",             60              => "minute",             1               => "second");  $passed=time()-$date;  if($passed<5) {     $output='less 5 seconds ago'; } else {     $output=array();     $exit=0;     foreach($times $period=>$name)     {         if($exit>=$precision || ($exit>0 && $period<60))    break;         $result = floor($passed/$period);          if($result>0)         {             $output[]=$result.' '.$name.($result==1?'':'s');             $passed-=$result*$period;             $exit++;         }          else if($exit>0) $exit++;      }     $output=implode(' , ',$output).' ago'; }  return $output; } 

i entering date using: $date = date("y-m-d h:i:s");

is $passed=time()-$date off?

thanks everyone!

you using $date = date("y-m-d h:i:s"); input, return akin 2013-05-13 02:04:05 right now. call time() return value near 1368403494. subtract 2 eachother, , date string implicitly silently converted integer php, 2013. means it'll see post 1368403494 seconds ago, not entirely accidentally ending somewhere in january 1970, start of unix timestamp age. yep, that'll 43 years , few months old.

don't mix string , integer arithmetic, php's silent conversions make them hell.
