Review comment:
We do not need Powermock at all in these tests. We can remove all the mocks
and add our own clock.
```
new Clock() {
@Override
public long currentTimeMillis() {
return TEST_TIME_IN_MILLIS;
}
}
```
In general I am against mocking classes (if possible to avoid it) as this
code maintainability more tricky.
