Streaming videos seem to have three-to-five minute differences in launch time.

There are multiple channels; be sure to find the correct one. But you will know if you have the correct one it will be very, very live. Right now, discussing the well-known helium leak which will not interfere with launch.  

Launch time dependent on "position" of launch site relative to earth's rotation. 

On another note: remember the days when CBS, NBC, and ABC would be televising "these" launches, constantly interrupted by commercial advertising. Here we have NASA's own television network, being streamed live on YouTube and no cost to viewers. 

More and more agencies / corporations will develop their own "television networks." All they need is one camera. With generative AI, they may not even need a "real live person" to televise "live news." 

"Biden TV"? 24/7.

"Trump TV"? 24/7.

"GM TV"? 24/7.
