Java8 Date/Time formats

Hi, Maybe I’m missing something so apologies if this is not an issue. I’ve configured my spring boot application to use jackson-datatype-jsr310 by including in pom.xml, all outgoing json is serialized correctly. however I am using a hashmap to set the payload of the the jwt token:

hashMap.put(Claims.ISSUED_AT,LocalDateTime.now);

and this is being serialized in the Long LocalDateTimeFormat:

{"hour":9,"minute":53,"second":49,"nano":288000000,"dayOfYear":193,"dayOfWeek":"WEDNESDAY","month":"JULY","dayOfMonth":12,"year":2017,"monthValue":7,"chronology":{"calendarType":"iso8601","id":"ISO"}

I had a similar issue in another spring boot application where I was using new ObjectMapper() and not using springBoots configured ObjectMapper. Any ideas how I could make jjwt pick up springboots ObjectMapper which would be configured correctly ? I’m using using jjwt version 0.7.0.

Thanks in advance for your help, Peter

I would not support LocalDateTime. LocalDateTime is not an instant and therefore does not identify a point in time. You would need a time zone for that. Which means you don’t know how much time has passed since a claim was issued which means that you don’t know whether it is expired.

Even the JSR-310 expert group leader thinks LocalDateTime is not generally useful. https://github.com/tc39/proposal-temporal/issues/7#issuecomment-288997620

@RockyMM sure, Instant, OffsetDateTime and ZonedDateTime are a great addition and completely fine.
