Hi all,

I'm having some problem with piwigo installation. Here is the message from system:

Strict Standards: date(): 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 'America/New_York' for 'EDT/-4.0/DST' instead in /homepages/22/d531928679/htdocs/longvic/admin/intro.php on line 116

How could we solve this problem ?
