PHP strtotime()でWarning


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 ‘Asia/Tokyo’ for ‘JST/9.0/no DST’ instead in ‘スクリプト名’ on line 10, referer: ‘リファー’



php.ini の date.timezone に Asia/Tokyo を設定してやればOK。
