Aaw, of course you are right. I changed the code for another test and
forgot  to revert the change when I copied it into the mail.

So it seems like there is a bug. But what makes me wonder is that HHVM
prints out the same result. That's why I wanted to ask this mailing list as
I assume that I am missing something :-/

Does anyone have an idea?


What time zone are you using? The difference may be related to daylight
savings/summer time as that changed in that specific period.


Best regards
