There was no plan yet to do so. It would require a custom component for an interceptor in your case.
Though if someone made a component ready for that I would be happy to migrate it into nowicket.
Theoretically we could let the binding generator automaticallly instantiate it when the input field has type "datetime", " time" or "datetime-local" . For datetime case with both a date and time picker, for time case only for the time picker. The date picker would still operate on the "date" input type as it already does. The binding could operate as it does already on Date, Calendar, FDate, LocalDateTime. Though a policy would need to be introduced on how to initialize a time in that case when no reference date is available.
Since now we lacked the need to support this directly in NoWicket.
