I agree that 30 seconds is exactly the right amount of time for me to go back to what I was doing and then be weirdly surprised by the lag spike. I never realized that 30 seconds was such a long time in this game, but apparently it is, especially if you're in a hurry to get things done before sunset. The day length makes a person feel like they have to keep moving all the time.

I wish they would put it right after the Good Morning message or something that is in-game predictable like that.
