Hello, im found some strange behaviour. Someone knows whats is going on or it is a bug?:
lets do like this:
three dates in timestamp:
27.10.2007: 1193436000
28.10.2007: 1193522400
29.10.2007: 1193612400
convert back:
1193436000: 27.10.2007 00:00:00
1193522400: 28.10.2007 00:00:00
1193612400: 29.10.2007 00:00:00
And one day is always 24 hours * 60 minutes * 60 secondes = 86400. So the difference between these
three dates in timestamp should also be the same.But:
day2-day1 = 86400
day3-day2 = 90000
Here is my code, im using PHP Version 5.1.6:
echo ' three dates in timestamp: <br>';
$day1 = mktime(0, 0, 0, 10, 27, 2007);
$day2 = mktime(0, 0, 0, 10, 28, 2007);
$day3 = mktime(0, 0, 0, 10, 29, 2007);
echo '27.10.2007: '.$day1.'<br>';
echo '28.10.2007: '.$day2.'<br>';
echo '29.10.2007: '.$day3.'<br><br>';
echo 'convert back: <br>';
echo $day1.': '.date('d.m.Y H:i:s',$day1).'<br>';
echo $day2.': '.date('d.m.Y H:i:s',$day2).'<br>';
echo $day3.': '.date('d.m.Y
H:i:s',$day3).'<br><br><br>';
echo 'And one day is always 24 hours * 60 minutes * 60 secondes = 86400. So the difference
between these three dates in timestamp should also be the same.But: <br>';
echo 'day2-day1 = '.($day2-$day1).'<br>';
echo 'day3-day2 = '.($day3-$day2).'<br>';
