@GwtCompatible
public class FakeTicker
extends com.google.common.base.Ticker
```
A Ticker whose value can be advanced programmatically in test.
The ticker can be configured so that the time is incremented whenever read() is called: see setAutoIncrementStep(long, java.util.concurrent.TimeUnit).
This class is thread-safe.

Method Detail

advance

@CanIgnoreReturnValue
public FakeTicker advance(long time,
                          java.util.concurrent.TimeUnit timeUnit)

Advances the ticker value by time in timeUnit.

setAutoIncrementStep
```
@CanIgnoreReturnValue
public FakeTicker setAutoIncrementStep(long autoIncrementStep,
                                       java.util.concurrent.TimeUnit timeUnit)
```
Sets the increment applied to the ticker whenever it is queried.
The default behavior is to auto increment by zero. i.e: The ticker is left unchanged when queried.
