the local time label for raid auto launch is tied to your device so it should change when your device time changes. I know this because I went in with a Emulator set to wrong local time for me and all the local times for raid auto launch confused me till I figured out what I did. go test it out. manually set you device time back an hour then reload the game and look.
So if you want to keep auto launch at the same UTC time no change needed.
if you want to keep auto launch at the same local time then you will need to change it after dst ends
