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)
