Bug #54655 [Opn->Nab]: unable to compare timezones instance with == operator

Edit report at https://bugs.php.net/bug.php?id=54655&edit=1 ID: 54655 Updated by: heiglandreas@php.net Reported by: giorgio dot liscio at email dot it Summary: unable to compare timezones instance with == operator -Status: Open +Status: Not a bug Type: Bug Package: Date/time related Operating System: any? PHP Version: 5.3.6 Block user comment: N Private report: N New Comment: Comparing two classes with "==" checks whether both are instances of t he same classes. If you want to compare also whether they are the same you have to use "===" to do so. Have a look at https://3v4l.org/EZQnF Regarding the comparison <= or >= the main question arising is: What makes one timezone higher or lower than the other one? You can not rank timezones.
