Change TimeZone in Docker containers

With Docker Engine

The timezone of a container can be set using an environment variable in the docker container when it is created. For example:

$ docker run ubuntu:latest date
Sat Feb 27 15:58:32 UTC 2021
$ docker run -e TZ=America/Bogota ubuntu:latest date
Sat Feb 27 15:58:40 Asia 2021

WSL 2 GNOME Desktop

Think Xfce looks dated? Want a conventional Ubuntu experience? This tutorial will guide you through installing Ubuntu's default desktop environment, GNOME.
