### Question:
FakeUtils extends AbstractCaller { @UtilityMethod public final String ExpireTime(String dateFormat, String format, String timeZone) { return DateUtil.formatDateTime(dateFormat, format, timeZone); }  @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 testExpireTime() { LocalDateTime localDateTime = DateTimeUtility.nowLocalDateTime(); System.out.println(localDateTime); System.out.println(instance.ExpireTime("Y+1:M+1:D+1:h+1:m+1:s+1:ms+1", "yyyyMMdd-HH:mm:ss.SSS", "UTC")); System.out.println(instance.ExpireTime("Y+1:M+1:D+1:h+1:m+1:s+1:ms+1")); assertEquals(instance.ExpireTime(LocalDateTime.of(2005, 6, 7, 8, 9, 10, 11_000_000)), "20050607-08:09:10"); }
