Question

I’m using timestamp in my php script to handle time in hours, minutes and seconds. Timestamps also record the date but I’m only using time 00:00:00.

For instance I’m caluclate difference in time

$start = strtotime("12:00:00");
$end = strtotime("20:00:00");

$difference = $end - $start;

or dividing time

$divide = $difference/3;

Should I continue using timestamps for these operations or is there a time-specific function in php?

An example of how to do this with DateTime:

$d1 = new DateTime('11:00:00');
$d2 = new DateTime('04:00:00');

$diff = $d1->diff($d2);

echo $diff->h, " hours ", $diff->i, " minutes\n";

Output:

7 hours 0 minutes
