### Question:
JodaISO8601UTCCurrentDateAndTimeFormatter implements ISO8601UTCCurrentDateAndTimeFormatter { @Override public String getCurrentDay() { DateTime dt = new DateTime(); DateTime utc =dt.withZone(DateTimeZone.UTC); StringBuilderWriter b = new StringBuilderWriter(24); try { formatter.printTo(b,utc); } catch (IOException e) { } return b.toString(); }  @Override String getCurrentDay(); @Override String formatToUTC(String day);  }### Answer:
@Test public void testCurrentDayReturned() { SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd'T'HH:"); Date d = new Date(); System.out.println(formatter.getCurrentDay()); assertTrue(formatter.getCurrentDay().startsWith(f.format(d))); }
