 Using the [`--runonce`](#update-all-containers-and-quit-ouroboros) arg tells ouroboros to make one pass updating all/specified containers and then exit.
 
+### Timezone Configuration
+
+To more closely monitor ouroboros' actions and for accurate log ingestion, you can change the timezone of the container from UTC by setting the [`TZ`](http://www.gnu.org/software/libc/manual/html_node/TZ-Variable.html) environment variable like so:
+
+```
+docker run -d --name ouroboros \
+  -e TZ=America/Chicago \
+  -v /var/run/docker.sock:/var/run/docker.sock \
+  circa10a/ouroboros
+  ```
