Squashed commits: e94f7bf9 epicardium/rtc: add monotonic time e0691c6d pycardium/modules/utime.c: add bindings for monotonic time 756c13df epicardium/rtc: fix numerically unstable subsecond decoding the subsecond encoding function from epic_rtc_set_milliseconds and the corresponding decoding function from epic_rtc_get_milliseconds are not numerically stable. i.e., encoding 5 milliseconds to 20 subsecs and immediately afterwards decoding that yields 4 milliseconds. Adding a bias of 999 (0.24 milliseconds) to the decoding function makes it numerically stable, while never decoding any subsecond value to more than 999 milliseconds. e99e278b epicardium/rtc: only poll time once for calculating monotonic_offset 18936b7e pycardium/modules/utime.c: run clang-format 869ac617 epicardium/rtc: add explanation comment for numerically stable subsecond decode
