As of build 22621 of Windows 11, the seconds display can be switched on again via RegEdit or special programs. Previous versions did not allow this even with tools. In later Windows 11 versions, the seconds should be displayable (or not) via a checkbox in the settings, or from the named version (22621) number via RegEdit: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced. Create a DWORD there called ShowSecondsInSystemClock with the value 1. An update has just been performed, before the update there was no seconds display. With the update, the seconds display was turned on, probably due to a command on my part that had already happened.
