I've written a views query handler that pulls data from a web service call. There is a date field (i.e. uses views_handler_field_date to do render of the field) that seems to be treated correctly as a date field, that is I can change the formatter of the field for example and the field displays correctly. I would like to display my results using a calendar view but I it is not in the list available when I go the "Add view from template" screen. I suspect that I may have to do more to get Calendar to pick up my data, but I thought I would try and find out if what I'm doing is even possible.
