Classes
class	hops::hops_clock
	a clock for hops-time stamps, measures time in (UTC) nanoseconds since J2000 epoch. Functionality modelled on the gps_clock from the 'date' library (requires the timezone tz library too). Relys on the H. Hinnant date library (and tzdata), this library is expected to be adopted into cxx-20 standard More...
