Hi folks
I first thought that this was an artifact in the zoom levels, but then realized that it is rather a question of time (the Shenzhen airport got a second runway around a decade ago and thus, the higher zoom level seems to be older image data). So my question is: Is there a way to tell how old the image data is?

I recently ran into this same issue myself. This is something the imagery provider would need to include. For example, this ArcGIS imagery provider allows you to click on a location on a map and get some stored metadata: https://sandcastle.cesium.com/index.html?src=ArcGIS%20MapServer.html
The Cesium ion Bing Imagery layer does not have such information, but it does look like the Bing API has a separate route for obtaining this information, so it may be technically possible in the future. See the “vintage start” date in this route:

If you need a small part of the area, then you can try using the ImageProvider interface, more precisely, the classes based on it. Here is an example
