Hi I cleaned my music collection with Mp3tag and now it's in excellent form, but..  
All tags that going from one program to another are staying right, except.. yes, this is realasetime.

I tried in MusicBee and Traktor.

Firslty I used format YYYY-MM-DD, than, by your (ohrenkino) advice from [here](https://community.mp3tag.de/t/16556/2) I tried YYYY-MM-DDThh:mm:ss but it's still has format YYYY/1/1 in Traktor end empty in MusicBee.  
If I use YYYY/MM/DD it's still YYYY/1/1/ in Traktor.

I didn't found any solutions more. Maybe have any ideas how to keep it everywhere?
