Question

I would like to show any give time in hours only.

Example:

Unix timestamp: 169200

Which is equal to 1 day and 23 hours…

But how can I convert this to hours so it shows 47:00:00 (47 hours)?

Thanks

Edit: It must show minutes and seconds too 😉

Answer 1

A unix timestamp is a number of seconds. There are 60 seconds per minute, 60 minutes per hour. So to convert from seconds to hours, divide by 60*60 = 3600.

If you need the minutes and seconds as well:

$timestamp = 169200;

$secs = $timestamp%60;
$mins = floor($timestamp/60);
$hours = floor($mins/60);
$mins = $mins%60;

printf("%02d:%02d:%02d", $hours, $mins, $secs);
