void setNow(nanoseconds timeSinceEpoch)
Explicitly set clock to timeSinceEpoch.

void advance(nanoseconds duration)
Advance unit test clock by duration.
Class implementing custom system or steady clock behavior.
UnitTestClock(nanoseconds startTime=ClockTraits::getDefaultStartTime())
Clock that can be used in unit tests for time-dependent tests independent of wall clock.
BaseClock::time_point getNow() const override
System clock.
Definition: time.hpp:186
BaseClock::duration toWaitDuration(typename BaseClock::duration d) const override
static nanoseconds getDefaultStartTime()
Traits for UnitTestClock, defining default behavior for different clocks.
