Don’t like the normal date display in Ubuntu? It can be slightly modified using the usual methods, but if you want full customization you can do so with a tool called the dconf Editor. It’s a part of the dconf-tools package:
sudo apt install dconf-tools
Once you have it installed you can then run the dconf Editor. To create your own custom display for the time and date, dig down to this location:
Com –> Canonical –> Indicator –> Datetime
Change the time-format to “custom” and enter your desired pattern. I used this:
%a %d %b %H:%M
or
| %a %d %b %Y | %H:%M |
or
| %Y-%m-%d %a | %H:%M |
Feel free to experiment with other variables. This first configuration gives me day date month 24-hour:time.
Have fun with that.
