In the ASIAIR, when looking at the app, there are actually two times.
There's the time in the top left corner. This is the time at your location/ time of your device. Let's call this the App Time.
Then there's the Mount Time which you can see when you enable the mount in mount settings.
During DST the Mount Time will be one hour behind the App Time. You'll also always see the ⚠️ message about DST. This is how it should be. (See screenshot attached)
So, when DST ends, the App Time will go back one hour - but the Mount Time should remain unchanged.
Now, whether the ASIAIR looks at the App Time or the Mount Time for certain functions... not sure.
