If I get all Playlist Items with the Youtube Data API v3, I am getting this format for all videos:
"contentDetails": {"videoId": "KUL_AHeC4zw","startAt": "PT0S","endAt": "PT21M12.667S" }Whats that thingie next to endAt? Why is there a point in the middle? I expect some kind of PT21M54S. I just want the duration as I would get it when I am fetching a single video. Is that a bug or am I just not able to understand that ISO Date Format?
