减法后错误的时间

Question

Hello I am using strtotime function to subtract time but I am not able to getting such true value of it.

$time = strtotime('00:00:00');
$time1 = strtotime('23:00:00');


$t = $time - $time1;

echo "diff".$t1 = date('H:i:s',$t);

But am getting $t = 2:00:00 Instead of i get 1:00:00

Any one have idea whats gone wrong ?

Answer 1

$time = strtotime('00:10:00'); $time1 = strtotime('23:00:00');

$t = $time - $time1;

$hours = floor(($t - (($t/ 86400)* 86400)) / 3600);

$minutes = floor(($t - (($t/ 86400) * 86400) - ($hours * 3600))/60);

echo "
".$hours.':'.$minutes;

its give you right diff. time for same days .
