Would you be so kind as to show (snippets from) sample output with this change? I think having this sort of data available will be quite useful, just curious how it will look in practice.
Why is this on by default rather than guarded by a -DWITH_TIME_MAKE? It's clutter that's printed with no context and should not be of relevance to the vast majority of people building FreeBSD.
