Yes, but even being an Announcement subclass is debatable.

If you can announce any object, then you do not need Announcements either :).

Yes, I mentioned this already several times: traits listing expected protocol would be good. Maximum polymorphism, latest possible binding, no dependencies, composable.

Agreed. All I said is that to find the useful protocols we need to build the tools and not stop the discussion at the recording part of the logging.

I first of all want no dependency so that different logging backends can be plugged in or used. I think that this takes away any lock-in anxiety from people like myself, which will increase adoption.

I do not understand that. First, we talk about a handful of lines of code. Second, actually your newest implementation already ships a more specialized version of Beacon, so from this perspective Zinc already binds me at least to Announcements. Is this a bad thing? I think it is rather pragmatic.

BTW, it is ZTimestamp not ZnTimestamp, it has absolutely nothing to do with Zinc. ZTimestamp is second precision, UTC only, and takes half the size. It comes with cool formatting/parsing, full timezone and basic SNTP support.

Yeah, my bad.

No, I want all users to be able to make there own choices for whatever reason (efficiency, precision, portability). The timestamp is the only concrete element we can discuss now, but there could be others.

Freedom is good in the sense that people should be able to customize anything they want. At the same time if you want to provide services on top, you need to find a useful commonality. In our concrete case, I see no reason to keep DateAndTime when the other one is better.
