  - advanceTime
```
public void advanceTime(long duration,
                        TimeUnit timeUnit)
```
    Advances the time by the given duration. Time can also move backwards by supplying a negative value. This method performs no overflow check.
  - advanceTime
```
public void advanceTime(Duration duration)
```
    Advances the time by the given duration. Time can also move backwards by supplying a negative value. This method performs no overflow check.
