A lightweight (6kb~), console-based, reliable, opensource, all in one timer for Black Desert Online all written in Python.
It collects data from mmotimer.com, and then computes the countdown on its own.
It will save your server preferences, but if you wish to change the server to look for just delete the preferred_server.txt file.
You will need to install the requests library, by typing in your console:
pip install requests

I compiled it with autopytoexe. It will take some time to load (about 5 seconds).
Warning!
(thanks to Draconis from the Kakao Games Discord server.)
When you download the .exe, your browser might detect it as a virus. It usually happens with programs that have got too few downloads. The VirusTotal Scan shows that it's not harmful, at best it gets detected as a "Heuristic threat". In any case, remember that you can always use the Python file, as it is opensource and you can just look at it.
