You mean the time which is displayed in the log? Simply find your php.ini (usually at /path/to/your/server/bin/php7/bin/php.ini) and set date.timezone to your timezone http://php.net/manual/en/timezones.php
I just found php.ini-development and php.ini-production made the change in the 2 and it still did not work
if I rename them to php.ini they become ema '' Configuration Parameter '' and there is already that file!
