solve !
it was actually the language setting in the browser that define the 12 hour edit mode.
i changed to german and no the 24 hours are shown.
Sorry
many thanks for sharing
I tried with your code and still face same issues .
He input field still has 12hour with AM/PM
the footer is only shown when i change back to state
footer: =items.StartZeitBewaesserungVentil4.state
String StartZeitBewaesserungVentil4 <time> (gBewaesserungComputer) { stateDescription=""[pattern="%tH:%tM"]}
the displaystate showns error
