How to show the current timezone near time and date in the menu bar in Ubuntu 16.10? This should be relevant for the other versions also. It is a very missing feature, you can easily be confused without it. I would like to get something like "Fri Dec 23 20:35:05 (Europe/Kiev)".

Also it would be nice to be able to customize that string arbitrarily, say "Friday, 23.12.2016 - 20:35:05 (Europe/Kiev)". Thank you!

Update

Referring to How to change the date format? one can do

gsettings set com.canonical.indicator.datetime time-format "'custom'"

gsettings set com.canonical.indicator.datetime custom-time-format "'%a, %d.%m.%y - %H:%M:%S (%Z)'"

which changes the system time and date indicator to

Friday, 23.12.2016 - 20:35:05 (EET)

As you can see, everything is fine now, besides the timezone name. I set my timezones at Time & Date settings > Clock > Choose Locations. Then, if I write timedatectl in terminal I get

Time zone: Europe/Kiev (EET, +0200)

So, there are several options for a timezone name and it seems that it is strftime function that decides which one to use and also that just by feeding it with a format string there is no way to get a timezone name "Europe/Kiev" (only "EET" or "+0200").

So are there any ways to choose a timezone's name format?

Maybe using Serg's script I could place the preferred name next to the system indicator?

Thanks!

  • Not possible with default indicator, as far as i know, but I can make a separate indicator that displays just the time zone – Sergiy Kolodyazhnyy Dec 23 '16 at 20:07

Introduction

The indicator presented below displays current timezone in the top panel. The way it works is fairly simple. Timezone settings are set in /etc/timezone file. All the indicator does, is read that file, and update the information displayed if necessary.

Save the source code below as ~/bin/timezone_indicator , run chmod +x ~/bin/timezone_indicator to make it executable, and run as ~/bin/timezone_indicator. If you wish for it to start each time you log in automatically, open Startup Applications menu, and add the full path to the indicator as one of the commands there.

enter image description here

Feel free to test changing the timezone as show in https://askubuntu.com/a/524362/295286

  • Thanks for this, works great and solved my need perfectly! Next step is to make a PPA for this! – Elijah Lynn Dec 13 '17 at 16:58

If you can obtain the timezone in a format you're happy with from a terminal command, you could then install Sysmonitor Indicator and add that command (as a script).

You could go further and disable the default clock (there's an option to hide it). Your script/command would then display the date/time/timezone to your liking.

  • This isn't a practical solution, it just gives a script after you click on it. It doesn't display the output/return of the script in the indicator. – Elijah Lynn Dec 13 '17 at 16:54

    I linked to the wrong indicator; hopefully fixed. – Bernmeister Dec 16 '17 at 3:15
  • Much better answer now! Now what would make the answer better is an example to use with that indicator. Especially one that runs every X seconds if there is a chance of it replacing the system installed time indicator. – Elijah Lynn Dec 18 '17 at 19:05
