+* Replace `TZ=Europe/Paris` by your [server timezone](http://php.net/timezones), or remove the line to use `UTC`.
 * If you cannot have FreshRSS at the root of a dedicated domain, update the command above according to the following model:
 	`--label traefik.frontend.rule='Host:freshrss.example.net;PathPrefixStrip:/FreshRSS/' \`
 * You may remove the `--label traefik.*` lines if you do not use Træfik.
