I’m going to confess here, I was a bit lazy. I decided that, because I could create the time program, I rewarded myself by adding a native ISO 8601 time output command io text iso rXX. Elegant? Yes. Low-Level? Not as much as I would like. But the choice was either make a single line of code to simplify programs like this massively, or wire in a tediously made, messy 350 line program that doesn’t fully account for the 400 leap year rule or leap seconds. Hmm…

TLDR; I caved to simplicity. But CrawFS file listing from boot now display file genesis time!
