I saw the news of timestamp extension support on version 0.9.0 and tried it. But I still can't (de)serialize timestamps with the 0.9.3 version. Is it supported also when using Jackson?
I did like this and the "Instant" was serialized as a map of string keys "epochSecond"/"nano" and uint32 values.
private static class A {
@JsonProperty(index = 0)
Instant instant = Instant.now();
}
....
A a = new A();
ObjectMapper objectMapper = new MessagePackMapper();
byte[] bytes = objectMapper.writeValueAsBytes(a);
