- Move time json marshaling to the jsonlog package: this is a docker internal hack that we should not promote as a library. - Move Timestamp encoding/decoding functions to the API types: This is only used there. It could be a standalone library but I don't this it's worth having a separated repo for this. It could introduce more complexity than it solves.
