        return DateTimeZone.getAvailableIDs().stream().collect(Collectors.toMap(id -> id, DateTimeZone::forID));
    }//  w w  w  . j av  a 2s . com

    File directory = new File(source);
    if (!directory.isDirectory()) {
        throw new IOException(directory + " is not a directory");
    }
    File[] files = KNOWN_FILES.stream().map(f -> new File(directory, f)).toArray(File[]::new);
    ZoneInfoCompiler compiler = new ZoneInfoCompiler();
    PrintStream out = System.out;
    // Ignore standard output while compiling...
    System.setOut(new PrintStream(new ByteArrayOutputStream()));
    Map<String, DateTimeZone> zones = compiler.compile(null, files);
