Since the installation of Juno, the time that appears on the logon screen is in English format (AM/PM), while French is the language defined in the settings, and the time and date are displayed correctly everywhere else. Is there a setting to fix this, or maybe it's a bug ?
Before you install Juno, you choose your time zone in the installation wizard. This seems to affect the system date/time/language settings. So when I booted up, the system showed me a date in Arabic (based on my time zone) and after logging in the date time in the bar at the top would be US/English format. In System Settings -> Language & Region, I had to "Unlock" additional permissions, then press "Set System Language". This should change the login screen to French. This is the same behavior from Loki and Freya as well.
