### Question:
FixedTimestampProvider implements ModificationTimeProvider { @Override public Instant get(Path local, AbsoluteUnixPath inContainer) { return fixed; } FixedTimestampProvider(Instant instant); @Override Instant get(Path local, AbsoluteUnixPath inContainer);  }### Answer:
@Test public void testApply_file() { Assert.assertEquals( Instant.ofEpochSecond(1), fixture.get(file.toPath(), AbsoluteUnixPath.get("/"))); }
@Test public void testApply_directory() { Assert.assertEquals( Instant.ofEpochSecond(1), fixture.get(directory.toPath(), AbsoluteUnixPath.get("/"))); }
