I have streaming which has a start date and an end date as unix time stamp as follows:

"startTime": 1489041394000,
"endTime": 1489041538000

From this times how can i calculate the duration of this video using php?

Answer 1

Try this code

$startTime = 1489041394000;
$endTime = 1489041538000;
$duration = $endTime - $startTime;
$durationInTimeFormat = date("H:m:s", $duration); //
$sec = intval($duration % 60);
echo $sec;
