java9+ OffsetDateTimeSerializer/OffsetDateTimeDeserializer miliseconds instead of nano config

Hi,
we have set `SerializationFeature.WRITE_DATES_AS_TIMESTAMPS` to `false` and in java8 it wrote time in milliseconds precision (java worked this way for a long time).
After migrating to java11 the precision is nanoseconds
* (Java 8- - 2020-01-28T16:31:37.698+01:00)
* (Java 9+ - 2020-01-28T16:31:37.698185+01:00)

This is fine, but unfortunately the services both northbound and southbound of our system can work with milliseconds (3 digits).
Would it be possible to create a `SerializationFeature` to enable java8 behavior meaning serializing only to milliseconds precision?
We use a spring boot autoconfiguration where we would like to set this globally for all of our microservices.

Thanks,
Ondrej

PS: Maybe until then, could you provide us instructions for the best way to setup this in Spring Boot 2.2.x?
Thanks
