Some controllers (like Arduinos) can only count using 32bit variables.
If they're counting milliseconds, they can count until ~50 days.
This means that if we want to allow longer operation times, we should reset the mutual time once in a while (every day should be more than enough)
This has to be checked for every supported controller. if some controllers have less than 32bit variables or if they count microseconds, another update frequency is needed.
