mise à jour

Suite à la mise à jour de PHP5 sur un systeme linux OpenSuse, il a fallut procéder également à celle de SPIP 1.9.2 pour La dernière version SPIP 2.1.0. Celle ci a été effectuée suivant les recommandations de migration du site : spip.net/

Après mise à jour le message suivant apparait en tête de page :

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.
