If you use a deprecated Timezone somewhere and don't know it, it's hard to track down...(no exception) I only found it "randomly" today, that i've used it there and all time data in the database are not correct... If you use something like: \DateTime::createFromFormat('Y-m-d H:i:s', '2013-09-09 14:49:00', new DateTimeZone('CET')) Just the default timezone from ini will be used and therefor the dateTime value is wrong if you save it or display it somewhere...
