Sigh. %N is a good feature to have but 30 lines of code to add it makes
me wince, and it's one of those "eh, both sides have a strong argument"...

Lemme see what I can clean up here...

(You're right that --full-time is already in, and tests rewritten to use
that would be merged as-is. But that's not a reason _not_ to have %N,
nanoseconds are a thing these days and "date" should support them. Only
supporting them in one direction makes me sad, hwclock should support
them too, which usually involves spinning and re-reading to find the
edge if I recall... Did I already do that? I have a note but which todo
list it would be in... "ls todo*.* */todo*.* */*/todo*.* | wc -l" finds
50 files. "Collate todo lists" is a perennial todo item...)
