Sunset? Where did it go?

I am not sure how it happened. In a way you could call it missing time. A little while ago I was at my computer having a nice time playing a game, but then I glanced out the window. I saw a beautiful sunset occurring so I went outside and started working on my upper deck by the arbor and suddenly started reorganizing my nursery area, cleaning, etc. etc. etc. while also setting up for Aquaponics using some "feeder" goldfish I rescued a year ago.

Next thing I know it's right now, and very very dark. What happened to that sunset I went out to enjoy?
