When are the live views added to the view_count of the videos?

Hey,

since total views of a channel is deprecated I am using the view_count of the videos to get this number. But I noticed, the view_count is often 0 until they add the live views on this number. I just dont understand when this happens.
I track the view_count every 30 min and for this example the live views got added around 3am.

But this is not the same for all videos. Some got added at around 11pm, some at 9:30am.

Is this somewhere documented? Didn’t find anything about this topic.

Best regards,

Tolga
