On Hi-Fi Cast, I see a 4-digit year in Song Details. This is computed from the dc:date value sent by MinimServer to the control point. This value is required by the UPnP specification to be of the form YYYY-MM-DD.

I have checked the code in MinimServer for writing the dc:date value. Because of the requirement to send a YYYY-MM-DD value, displayFormat processing is not used for this value.

It looks like Hi-Fi Cast (and other control points I have tried) is showing only the YYYY portion of the YYYY-MM-DD value that MinimServer is sending.
