Exercise 1: Verifying upload time of Youtube video

On August 21, 2013, users uploaded several videos on Youtube depicting chemical attack in Syria. In response, Russian Foreign Ministry declared that the videos were fake, as they were uploaded several hours before the attack. Russia should have been based on the fact that Youtube indicated August 20, 2013, as an upload time of the videos.


Using Youtube Data Viewer we can see the exact upload time of the video which is August 21, 2013.


Why did Youtube show August 20?
