Strtotime(): It is not safe to rely on the system's timezone settings.

Jeżeli dostaniemy błąd:

Severity: Warning  --> strtotime(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Moscow' for 'MSK/4.0/no DST' instead controllers/adminapi.php 558

Otwieramy plik php.ini i odnajdujemy linijkę:

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
;date.timezone =

Zamieniamy na

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone =Europe/Warsaw

Oczywiscie przy zalozeniu, ze nasz system pracuje na "Europe/Warsaw" :)
