Druid adapter: Usage of range conditions like "2010-01-01 < timestamp" leads to incorrect results

  @Test
  public void testRangeCalc() {
    final Fixture2 f = new Fixture2();
    checkDateRange(f,
        f.and(
            f.le(f.timestampLiteral(2011, Calendar.JANUARY, 1), f.t),
            f.le(f.t, f.timestampLiteral(2012, Calendar.FEBRUARY, 2))),
        is("[2011-01-01T00:00:00.000Z/2012-02-02T00:00:00.001Z]"));
  }

java.lang.AssertionError: 
Expected: is "[2011-01-01T00:00:00.000Z/2012-02-02T00:00:00.001Z]"
     but: was "[1900-01-01T00:00:00.000Z/2011-01-01T00:00:00.001Z]"
