An implementation of FuchsiaSystemClockInterface that uses the UTC clock installed
in the runtime.
Public Methods
void FuchsiaSystemClock (async_dispatcher_t * dispatcher, inspect::Node node)Construct a |FuchsiaSystemClock| that reads the UTC clock passed to the runtime.

void FuchsiaSystemClock (async_dispatcher_t * dispatcher, inspect::Node node, const zx::unowned_clock & clock)Construct a |FuchsiaSystemClock| that uses the given |clock| to check if the clock is
started, but reads time off of the UTC clock passed to the runtime. This constructor is
only intended for testing this class.
