Hello @teooo! You don't need to change your UTC settings every time you power up. What's important is to be aware of the difference between your local time and UTC. In your case, if it's 11am (UTC+2), then it's 9am in UTC. Just make sure you perform your power-up actions within the correct UTC day to ensure they are counted for the Power Up Month challenge. Good luck and happy powering up!
Thank you for clearing it up 🙂
