php7dev change timezone with sed
php7dev comes pre-configured as being on UTC - these commands visually check that and set all instances to the correct timezone for the UK:
find /etc/ -iname php.ini -exec cat '{}' \; | grep "date\.timezone"
find . -iname php.ini -exec sed -i "s/date\.timezone = \"UTC\"/date.timezone = \"Europe\/London\"/g" '{}' \;
find /etc/ -iname php.ini -exec cat '{}' \; | grep "date\.timezone"
Then, probably, sudo service nginx restart && sudo service php-fpm restart
