Ubuntu Mate - Show and Customize datetime on tray

We need to use dconf-editor to customize our try icon panel. First we need to install dconf-editor:

sudo apt install dconf-editor

After that we need to navigate to com -> canonical -> indicator -> datetime and make some changes:

- custom-time-format: %A Y%/%m/%d - %H:%M
- show-date: enabled
- show-day: enabled
- show-year: enable
- time-format: custom

This is a screenshot with my config: dcong-editor
