Lately our clients noticed a discrepancy in the video length metric, as it seems like we're getting 2 different lengths in YT and in the API call.
For example, We got the duration from YouTube's API. (For the following video)CTM 1556 Google UAC CO 6s
API response shows 7 seconds.

On YouTube we see that the length is 6 seconds:
API docs

API call list (https://developers.google.com/youtube/v3/docs/videos/list) with contentDetails as "part" parameter.
Please help us understand why we are getting 2 different parameters, and what needs to be changed.
