That is one of the approaches I tried. I added a property called dateInMs, set the editorDataField to that name, and then overrode the get/set data, like what you mentioned. I could get it to display the correct date, but whenever I edited it, it would end up displaying NaN/Nan/Nan for the formatted date. I could see the millisec being changed to dates in the arraycollection (which isn't what I wanted), but I haven't been able to get them to stay millisec in the array collection, but display/edit as date objects. Very frustrating.
