Provide a detailed description of the proposed feature

brew config command outputs Core tap JSON date and Core cask tap JSON date. These date format is unknown format. I think ISO 8601 format is better.

What is the motivation for the feature?

This format don't write year. So we can't know year information.

How will the feature be relevant to at least 90% of Homebrew users?

I don't know

What alternatives to the feature have been considered?

I think ISO 8601 format is better.

No opinion on the format, but we should at least use a consistent one:

Core tap last commit: 41 minutes ago
Core tap JSON: 14 Feb 21:30 UTC

but we should at least use a consistent one:

Not necessarily. The inputs are very different so the outputs may be more useful as they are (which I tend to agree with on last commit being relative).
