Hello Naoto,  the use of `UTC` looks good to me. Since the failing `assertCurrentDate()` method is only called in `testEmptySysPropValue()`, should we perhaps limit this usage of `UTC` timezone to only that test?  The rest of test methods just verify that whatever value was passed to the `java.properties.date` system property was written out as a comment in the properties file and they don't assert any `Date` semantics.
