On February 26th, 0:30 AM in my time zone (GMT +1), I built my village claim. Very shortly afterwards, I started a timer (using Amber client) for 24 hours.

On February 26th, around 22:26, I got a notification that the timer had completed. I thought it was the client being wonky, but walking up to my idol confirmed - to my horror - that it was indeed already active, even though only 22 hours had passed.

Either idols and Amber are both wonky in a synchronized manner, or there's something wrong with the server-side timer making it run too fast. I had also noticed this earlier with things like leather completion being well over two hours sooner than expected, but I thought it was either me setting the timers wrong or the client being wonky. But this is definitely server-side.
