Okay.
If your location currently in daylight savings time - I.e. your clocks have moved forward one hour - then this should be situation:
Say your current local real time is 20:00 (so 8pm).
Then, the time in the top left corner of the ASIAIR App will also be 8pm.
However - the time under mount settings should be 7pm (I.e. the time without daylight saving time).
See the picture I've attached as an example. You can see that the Mount Time (not DST) is one hour behind the real (DST) time. That is how it should be.
