+
+In order to use a timezone other than UTC when running a
+Java application within a container, the `TZ` environment variable must be

+# Example run
+podman run -ti --rm -e TZ=EST mytzimage
+lrwxrwxrwx. 1 root root 29 Nov 3 08:51 /etc/localtime -> ../usr/share/zoneinfo/Etc/UTC
+Now with default timezone:

+Forcing UTC:
+Fri Nov 19 23:10:55 UTC 2021
