> RawLocalFileSystem's FileStatus uses {{File.lastModified()}} api from JDK.
> This api looses milliseconds due to JDK bug.
> [https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8177809]
> This bug fixed in JDK 10 b09 onwards and still exists in JDK 8 which is still
> being used in many productions.
> Apparently, {{Files.getLastModifiedTime()}} from java's nio package returns
> correct time.
> Use {{Files.getLastModifiedTime()}} instead of {{File.lastModified}} as
> workaround.
