➢ Encryption needs to be off the table. It's not just a bad idea, it provides no benefits. Time is not a confidential matter. If you have some use cases for encryption, please state them.

I am not so sure it provides no benefits.  We used to think that DNS was a public repository and that there were no privacy concerns, and it turns out we were wrong.  Sure, time itself is not confidential -- anyone can buy a watch :) -- but the story around the meta-data for time services is not as clear.
