 If you don't already have it installed, either follow the [Installation Guide](https://github.com/nicolargo/glances/blob/master/README.rst) for your system, or setup [with Docker](https://glances.readthedocs.io/en/latest/docker.html), or use the one-line install script: `curl -L https://bit.ly/glances | /bin/bash`.
 
+If you are using Docker to run glances make sure to add the enviroment variable `-e TZ = {YourTimeZone}`. You can get a list of valid timezones by running `timedatectl list-timezones` on any linux system. This is needed so the graphs show the currect time.

+Here an example for Docker
+```
+ docker run -d \
+    --name glances \
+    --restart unless-stopped \
+    -v /var/run/docker.sock:/var/run/docker.sock:ro \
+    -p 61208:61208 \
+    --pid host \
+    --privileged \
+    -e GLANCES_OPT=-w \
+    -e PUID=1000 \
+    -e PGID=1000 \
+    -e TZ=Europe/Zurich \

 Glances can be launched with the `glances` command. You'll need to run it in web server mode, using the `-w` option for the API to be reachable. If you don't plan on using the Web UI, then you can disable it using `--disable-webui`. See the [command reference docs](https://glances.readthedocs.io/en/latest/cmds.html) for more info.
 
 If Glaces is running on a Windows system it is recommanded to add the following arguments ```--disable-plugin all --enable-plugin cpu,mem,diskio,ip,network,containers,quicklook,load,fs,alert -w``` This is due to Glances not being that stable on windows, so disabling all plugins that aren't used by Dashy widgets can save on ressources.
