// Minimal native stand-in for Adafruit's RTClib.h. Real hardware boards pull
// this in transitively for helpers/AutoDiscoverRTCClock.h (not used by the
// sim build -- SimRTCClock.h reads the host wall clock directly) and for
// DateTime, which src/helpers/CommonCLI.cpp's "clock"/"clock sync"/"time"
// CLI commands genuinely construct and call hour()/minute()/day()/month()/
// year() on. Nothing in companion_radio (root files or ui-new/) uses
// DateTime, but CommonCLI.cpp (built for every board, including the sim) does.
//
// Implemented via the real C library's gmtime_r() (UTC calendar breakdown)
// rather than hand-rolling RTClib's own unixtime<->y/m/d/h/m/s conversion --
// same result, zero risk of a transcription bug in that math.
