Conclusion

You swapped the battery! No more steps required.

When you power on the alarmo, the clock will be set at 1AM at 01/01. It will be adjusted automatically after a few seconds if you have an internet connection set up. If you don't have an internet connection or it doesn't adjust after a minute, you can adjust the Time and Date at settings -> Date and Time.

Please throw your old battery in a battery collection point.
