### Question:
FakeUtils extends AbstractCaller { @UtilityMethod public final String ExpireDate(String dateFormat) { LocalDateTime localDateTime = DateUtil.modifyLocalDateTime(dateFormat); int year = localDateTime.getYear(); int month = localDateTime.getMonth().getValue(); int day = localDateTime.getDayOfMonth(); StringBuilder sb = new StringBuilder(); sb.append(year); if(month < 10) { sb.append(0); } sb.append(month); if(day < 10) { sb.append(0); } sb.append(day); return sb.toString(); }  @UtilityMethod final String ClOrdID(); @UtilityMethod final String ExpireTime(String dateFormat, String format, String timeZone); @UtilityMethod final String ExpireTime(String dateFormat); @UtilityMethod final String ExpireTime(LocalDateTime date); @UtilityMethod final String ExpireDate(String dateFormat); @Description("Returns the current date/time in the UTC time zone<br/>Example: #{getDateTime()}") @UtilityMethod final LocalDateTime getDateTime();  }### Answer:
@Test public void testExpireDate() { LocalDateTime localDateTime = DateTimeUtility.nowLocalDateTime(); System.out.println(localDateTime); System.out.println(instance.ExpireDate("Y+1:M+1:D+1:h+1:m+1:s+1:ms+1")); }
