Does php date_default_timezone_set set daylight saving time?

Question

Does php date_default_timezone_set support daylight saving time?

I have this code and am wondering if it will always lead to the correct Stockholm time?

date_default_timezone_set('Europe/Stockholm'); $timestamp = date("Ymd H:i:s"); 

Answer 1

Yes, this should always lead to the right time.

Answer 2

As long as your time zone is listed in the following link, the timestamp should be relative to the correct time zone.

Answer 3

PHP does not automatically handle DST. You have to check

 if (date('I', time()) == 1) ... the time is in DST mode ("0" = not) 

Then you should increase the time accordingly. (Note: “I” is in equity. I just checked it and it works.)
