Github user vvysotskyi commented on the issue: https://github.com/apache/drill/pull/904 @weijietong which problems did you have when tried to mock `System.getProperty()` method? As the example of nice mock of this method, you may use [this test](https://github.com/apache/drill/pull/936/files#diff-b053496903bff0dc154e42604b93b9efR60). Also besides the timezone, property with locale should be mocked.
