type: string
description: >-
  The date and time that the video was **published**. Note that this is often different from the time that the
  video was uploaded. For example, if a video is uploaded as a private video and then made public at a later time,
  this property will specify the time that the video was made public.


  There are a couple of special cases:


  - If a video is uploaded as a private video and the video metadata is retrieved by the channel owner, then the
     property value specifies the date and time that the video was uploaded.
  - If a video is uploaded as an unlisted video, the property value also specifies the date and time that the
    video was uploaded. In this case, anyone who knows the video's unique video ID
    can retrieve the video metadata.

  The value is specified in
  [ISO 8601 UTC](https://en.wikipedia.org/wiki/ISO_8601#Coordinated_Universal_Time_(UTC)) format.
