RP2040: time-keeping appears to have a problem after about 2^30 msecs #6452

User reports that long-running programs hang after about 12 days (maybe 2^30 msecs):

The problem: I am using an Adafruit Feather RP2040 with Circuitpython 7.2.x to constantly readout multiple sensors, e.g., a Bosch BME680, and save the data to a SD card. After roughly 12 days and a bit, no further data is saved and the microcontroller seems to stop working (neither properly exiting the code nor throwing an exception).

I suspect some tick overflow problem or similar.
