Comment 4 for bug 1182091

There should be a way to add special processing for fields in dbCommon that requires no updates to existing record supports. Then we could add a "virtual" field to dbCommon that automagically converts the TIME data to DBF_UINT64 on access. The mechanism to implement that is simple: instead of calling the record support's special method directly, first call the one for dbCommon; check via return value if that handled the field, otherwise invoke the record support's special.
