So if you wish for a way to represent time with short hexadecimal strings (doing away entirely with all the different factors in Gregorian time like 60, 7, 30 ±2, and 365) you got it. Stay tuned. If anyone anywhere likes it, I'll rewrite it in Kotlin, ditching dependency on Bash, dc, date, and coreutils. But I'll clean up and maintain the old bash functions too. I've been using them myself for enough years.
@travisfw I’m intrigued
@ssoper it's called #hexunixtime and I'll use that hashtag to announce when I publish. It's a simple thing, but honestly that's the best thing about it.

I documented and released hexunixtime bash utilities on Source Hut.
https://hg.sr.ht/~travisfw/hexunixtime/raw/README.adoc?rev=trunk
It's documented in asciidoc, which is somewhat less nice than markdown when viewed as a text file, but there is a browser plugin for asciidoc which will render the linked file in your browser effortlessly. If asciidoc is annoying, toot me and I'll just strip out the tables.

Clone like so:
`hg clone https://hg.sr.ht/~travisfw/hexunixtime/`
