@yorickausyps Or are you suggesting that Mp3tag should not write `TDRL` in ID3v2.3 because it is not defined in the official standard?

BTW: The official standard for ID3v2.4 describes timestamps as:

Perhaps I'm mistaken, but I understood that all these time-variants are valid:  
yyyy  
yyyy-MM  
yyyy-MM-dd  
yyyy-MM-ddTHH  
yyyy-MM-ddTHH:mm  
yyyy-MM-ddTHH:mm:ss  
**or with examples:**  
1987  
1987-12  
1987-12-31  
1987-12-31T23  
1987-12-31T23:59  
1987-12-31T23:59:59
