There's already two settings used by the template date and time filters (DATE_FORMAT and TIME_FORMAT), used for formatting in similar way as PHP's date(). Form fields like Date and Time, OTH, use strftime() formatting strings, and have hardcoded defaults.
It's common to inherit from those fields just for changing default formats and avoid boilerplate code (e.g, having to set date_format= in every form).
Those fields could, instead, make use of the DATE_FORMAT and TIME_FORMAT settings as defaults, if those are present.
