Wrong time display in Ubuntu Mate 20.10/22.04/22.10 when LC_TIME=pl_PL.UTF-8

[Robert Bycul]

The time applet on the panel displays time as: "YYYY:MM", YYYY being 4 digit year and MM 2 digit minute (see the attachment, the panel there is vertical, but doesn't matter, the issue is observed in horizontal panel too).
It looks as if it wanted to display both date and time instead of just the time, and probably it is trimmed because it's too long, so that only beginning and end of the date-time string is displayed.
(Localization: Poland, Time zone Europe/Warsaw).
The only way to fix it is to issue the following commands:
gsettings set org.ayatana.indicator.datetime custom-time-format '%H:%M'
gsettings set org.ayatana.indicator.datetime time-format 'custom'

(Of course it can also be fixed with the dconf-editor with the same settings).

The same happened on my two PC machines after upgrade from Ubuntu 20.04 to 20.10. I don't think that this is a problem with truncated display, as the time next to time zone localization is also displayed this way (see the attached screenshot).

[Piotr Jurkiewicz (piotrjurkiewicz)]

Steps to replicate:

1. Terminate ayatana-indicator-datetime-service.

2. Run in terminal:

    $ LC_TIME=pl_PL.UTF-8 /usr/libexec/ayatana-indicator-datetime/ayatana-indicator-datetime-service

The same problem with 22.04

[Rafał Myśliwczyk (mysliwczykrafal)]

Having the same issue with 22.10. After doing the following commands it fixed it partially:
gsettings set org.ayatana.indicator.datetime custom-time-format '%H:%M'
gsettings set org.ayatana.indicator.datetime time-format 'custom'

It still displays the wrong information if you click on the time to show the calendar. (pic attached)

This is supposed to be fixed in current version, however I was unable to build and install package locally because of dependency issues.
