We can use OGS as a clock (unranked game, “hit the clock” after each move by playing a random move in the OGS game) if you’re up for that. I’ve done it once before and it worked quite nicely.
Otherwise, I think I’ll just have to be content with some high amount of absolute time just to avoid the game sticking around forever if someone has to leave, but an agreement to play reasonably quickly so it ends long before time pressure
I just woke up, but I might try to go back to sleep, normally I wake up 2 hours from now. I’d be available from then until like 13 hours later (though not the whole time, I’ve got other things I want to get done today, too)
