Want to compare Timestamps in Drools

Question

I am to receive a timestamp value and want to check it agains the current timeStamp value to make sure that the value I am getting is less of before the current time stamp.

the value being sent is in this format 2022-05-13 17:52:07

rule "effectiveTimestamp is in past "
when
    $retail: DroolsDTO(pricingExecutionDetails.effectiveTimestamp != null &&
    pricingExecutionDetails.effectiveTimestamp.compareTo(java.sql.Timestamp.from(Instant.now())) >= 0 )
    $locale: Locale()
then
    modify($retail) {
        setIsValid(false),
        getViolationList().add(source.getMessage(config.pastEffectiveTimestamp, null, $locale))
    }
end
Copy

I think the java.sql.Timestamp.from(Instant.now()) has milli seconds attached to it - ex: 2022-05-13 19:14:21.371. am not sure if this matters when comparing

this is how the effectiveTimestamp field is defined in the DTO

  @JsonProperty("effectiveTimestamp")
  @JsonDeserialize(using = CustomDeserializer.class)
  @JsonSerialize(using = CustomSerializer.class)
  private Instant effectiveTimestamp;
Copy

this is the error I m getting

[2m2022-05-13 15:40:28.586[0;39m [33m WARN[0;39m [35m69147[0;39m [2m---[0;39m [2m[nio-8080-exec-3][0;39m [36m.w.s.m.s.DefaultHandlerExceptionResolver[0;39m [2m:[0;39m Resolved [org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Text '2021-11-30 17:52:07' could not be parsed at index 10; nested exception is com.fasterxml.jackson.databind.JsonMappingException: Text '2021-11-30 17:52:07' could not be parsed at index 10 (through reference chain: com.sams.pricing.rulesexecutor.dto.DroolsDTO["priceExecutionDetails"]->com.sams.pricing.execution.common.dto.PricingExecutionDetailsDTO["effectiveTimestamp"])]

(also I may have to change the >= 0 to < but thats just a side note still getting this parsing error )
