timestamp showing hour which is not there

[cloudll]

Hello,

 

I am comparing these 2 time stamps to see how much time has passed. They time passed is 66 seconds.

 

When I format them back into h:m:s, it shows 1 hour, 1 minute and 6 seconds instead of just 1 minute and 6 seconds.

 

I was just wondering why this was?

 

Thanks

$startStamp = 1487156507;
$endStamp = 1487156573;
$howLong = $endStamp - $startStamp;
echo $howLong . "<br>";
echo(date("h:m:s",$howLong)) . "<br>";

The date() function operates on Unix timestamps. Passing 66 to it means 1970-1-1 00:00:66 UTC. How this is displayed depends on the time zone.

 

If you want an interval like 66 seconds, you need to actually create an interval and format that.

try

$startStamp = 1487156507;
$endStamp = 1487156573;
$dt1 = new DateTime("@$startStamp");
$dt2 = new DateTime("@$endStamp");
echo $dt1->diff($dt2)->format('%H:%I:%S').'<br>';      //--> 00:01:06
