Hello, I wish to make a CCK Date field that allows for approximate historical dates. As far as I understand in D6 you can have a from and to date, but the granularity is applied to both fields, for every use of the field. If I made a new content type called Historical Figure, and had birth and death dates, I would want to allow the user to be able to enter different kinds of birth dates, like "circa 1634", "April 1837", "Summer 1919" or "late 1600's".
From a db perspective I imagine I could make it a combination of a date or datetime plus an enum, and some drupal hook would be responsible for turning the date+enum into the phrase.
What would be the best way of creating this new date field? I know the Date API has been extensively worked on, but am unsure how to hook into it. Should I just create a new date field type? Or try to use existing modules (say-- a multigroup of date + text area with the calculated fields module)? Thank you Jon
