7 characters in base32 (35 bits) is enough to count the milliseconds in a year.
So I could theoretically make a timestamp that looks like:
That's pretty usable for autogenerated urls, don't you think?
(These fun facts brought to you by thinking about pleromas new flake id system and ideas seen on rustodon's issue tracker)
An alternative would be to just use two extra characters for 45 bit timestamps, and count milliseconds after unix epoch. That way it's not expected to change in lockstep with any human calendar.
But then it's just semi-unreadable garbage all of it :/
