Functions
uint64_t	MonotonicClock::nowUs ()
template<typename Rep , typename Period >
constexpr std::optional< std::chrono::duration< Rep, Period > >	MonotonicClock::age (std::chrono::duration< Rep, Period > timestamp, std::chrono::duration< Rep, Period > now)
	Age of timestamp at now, both in the same unit; empty for a missing or future timestamp.
constexpr std::optional< std::chrono::microseconds >	MonotonicClock::age (uint64_t timestampUs, uint64_t nowUs)
constexpr std::chrono::microseconds	MonotonicClock::remaining (uint64_t timestampUs, uint64_t nowUs, std::chrono::microseconds lifetime)
	Time left before a receipt reaches lifetime; zero for a missing, future or expired one.
constexpr bool	MonotonicClock::fresh (uint64_t timestampUs, uint64_t nowUs, std::chrono::microseconds lifetime)
	Whether a receipt is younger than lifetime.
constexpr bool	MonotonicClock::withinAge (uint64_t timestampUs, uint64_t nowUs, std::chrono::microseconds maximumAge)
	Whether a receipt is at most maximumAge old, its limit included.
