Honestly, to me a day ratio is far more confusing and more to keep track of than just backdating things. It's been a little slow, but I don't think it's been all that bad. There's a steady pace at least.

Just give it a little more juice. Something like maybe routine investigations into the ruins with the scientists? I haven't checked to see if that's a thing or not... or maybe something like the town putting up quests to find or bring back resources, especially with the quarantine up.
