That was my first idea and when i found out the video url i was quite pleased to figure out the solution.

Then the "generated" folder made me think, and i decided to test it a bit more, so i started the experience at 15:00 and 35 seconds, just the right amount to get to the time reveal just after the clock change, and i was blown away, the video shows 15:01 and not 15:00 as i expected, whatever they are doing here to replace the video at the exact time without us noticing it is quite crazy.

I doubt they’re replacing the video at any point, it’s all probably prerendered videos for each time.

For a user who’s clock changes midplay, you would simply check the time with seconds before choosing the video to render, if it’s MM:35 or after you would play the MM+1 video instead of MM

Ah yes, that makes sense. I do remember seeing in the code that they add … 23 seconds? I think to the current time. I imagine that the time is shown in the video at the 23 secs mark?

So yes you’re right, they do take that (minute changes while watching the video) into account!
