Use the same key name for time in all events
Use the same format in all events
RFC3339 is the standard for this stuff and
for sure it should all be in UTC rather than
local time
This is a proposal to add schema, timestamps and unique ids to
events. For now just JS ones but I propose to do these for all
events the server sends that might be end user consumed.
These exist to help the user identify a message even if it was
sent to a 3rd party system, the schema will be translatable to
a well known url like https://nats.io/schames/jetstream/event/v1/obs_ack.json
or to another wll known identifier like a NATS subject name
We'd publish JSON schema documents at these well known locations
describing each key and so forth
