In journalctl I see error Settings schema 'org.ayatana.indicator.datetime' is not installed.

@tari01, what does dropping 'show-clock' setting mean? That there will be no clock in the indicators or it will not be shown by default?

Hmm... This smells like an installation issue. Could this be a duplicate of #15?

: ) Quite the opposite: there will always be a clock - that's the minimum we need to show.

@tari01, thank you for the clarification.

I did see the same error message as mentioned in #15, when reinstalling 'ayatana-indicator-datetime'.

I was able to fix panel clock issue by removing 'indicator-datetime' package. I saw a com.canonical.indicator.datetime.gschema.xml file under '/usr/share/glib-2.0/schemas/' and thought probably that is conflicting with org.ayatana.indicator.datetime.gschema.xml when "/usr/lib/x86_64-linux-gnu/glib-2.0/glib-compile-schemas" /usr/share/glib-2.0/schemas runs.

The clock is now visible in the panel and in journal I see, ಸೆಪ್ಟೆಂ 05 09:00:46 sai-HP-Laptop-14-bs0xx systemd[932]: ayatana-indicator-datetime.service: Succeeded.
