Time zones based upon anthropocentric concepts like countries have issues simply due to the realities of political changes. Entire countries and civilizations can come and go. The concept of even “common era” is a convention of convenience still based around a religious figure frankly, which is a sort of retcon given others through the same time period were likely measuring time in another coordinate system essentially. A self defining and self describing set of measurements would help here but obviously bloats formats similar to how XML schemas become overly verbose and pedantic without adding clarity to the target audience. So I agree that baking in a time zone is likely a bad idea but I have doubts we can do much better by trying to use another more absolute time coordinate system independent upon human civilization conventions.
