Question

I’ve got the following DateTime object in php:

[start1] => DateTime Object ( 
    [date] => 2012-05-21 12:59:59
    [timezone_type] => 3
    [timezone] => Europe/Berlin
)

[end1] => DateTime Object ( 
    [date] => 2012-05-21 22:36:00
    [timezone_type] => 3
    [timezone] => Europe/Berlin
)

and the result of:

$time->end1->diff($time->start1

is:

DateInterval Object ( [y] => 0 [m] => 0 [d] => 0 [h] => 12 [i] => 36 [s] => 2 [invert] => 1 [days] => 0 )

Why do I get an period of 12 hours and not 9?

Answer 1

I’ve found the solution…Before doing the diff I do a sub() on the start1 object. Now I’ve seen why my result is false… Here is the answer but I REALLY don’t why this is happening.
