* this wraparound-free 64-bit value to do a linear mapping to RTC time.
* System uptime on an nRF is maintained using the 24-bit RTC counter. We
* track the overflow count to extend the 24-bit hardware counter by an
* additional 32 bits. This then forms the basis for system time.
* RTC_UNITS_TO_MICROSECONDS() converts this into microsecond units (in
* 64-bits). We then shave off the lower 32-bits of it and add in the
* incoming timestamp to get a mapping into a virtual 64-bit timestamp.
