How to add a custom timezone clock to an XFCE panel?

Question

My local time is CET (Prague, EU), I also need to see UTC and, some times, MSK time. Can I add multiple clocks with different zones to a panel in XFCE? I know how to add multiple clocks, actually, but how to customize time zone of each of them?

Answer 1

It's possible to display multiple timezones by using multiple applets of the Orage Clock Panel.

Under Orage properties (right click on the clock -> properties) there is a button next to 'set timezone to:' labeled Open. Clicking that button will bring up a window that allows you to select which timezone you want that applet to use.

Each applet will use the timezone you set it for.

by the way, I noticed you state you use Arch on your profile... Orage isn't installed with the base xfce package under Arch-Linux... it is part of the xfce4-goodies meta-package:

$ pacman -Ss xfce4-goodies | grep orage

extra/orage 4.8.3-1 (xfce4-goodies) [installed]

Answer 2

According to Wikipedia, Orage can do this

It also includes a panel clock plugin and an international clock application capable of simultaneously showing clocks from several different time zones.

...almost, with its "Global Time" application which...

[...] shows time from any timezone. It can show several clocks at once and contains handy feature to adjust time. [...] Global time can be invoked from orageclock panel plugin by clicking middle button (=button 2) and it hides with the next click.

But I cannot find anything about this feature inside an applet...
