Timestap

[pero]

I have the following problem

When I subtract 2 (timestamp) dates, it reports back wrong time difference.


Can it be done like this at all?

$datee="2005-02-01 19:54:00"
$datee1="2005-02-01 18:58:00"

$date1=strtotim e($object["datee"]);
$date2= strtotime($obje ct["datee1"]);

$diff=0;

$diff = $date1-$date2;


$days = round($diff/86400, 0);
$hours = round(($diff%86 400)/3600, 0);
$minutes = round(($diff%36 00)/60, 0);
$seconds = $diff%60;

Tnx

Please post _runnable_ code - there's two parse errors and two undefined uses
of $object. Making minimal changes to your code so it runs and actually
displays something gives:

<?php
$datee="2005-02-01 19:54:00";
$datee1="2005-02-01 18:58:00";

$date1=strtotim e($datee);
$date2= strtotime($date e1);

$diff=0;

$diff = $date1-$date2;

$days = round($diff/86400, 0);
$hours = round(($diff%86 400)/3600, 0);
$minutes = round(($diff%36 00)/60, 0);
$seconds = $diff%60;

print "days: $days<br>";
print "hours: $hours<br>";
print "minutes: $minutes<br>";
print "seconds: $seconds<br>";
?>

Output is:

days: 0
hours: 1
minutes: 56
seconds: 0

Minutes are fine, hours are not. It's because you've used round. You want
floor; 56 minutes is 0.933 hours, so you want to round down, not up.

$days = floor($diff/86400);
$hours = floor(($diff%86 400)/3600);
$minutes = floor(($diff%36 00)/60);
$seconds = $diff%60;
