It's always weird to me how invisible Daylight Savings Time is. Every clock I own except the one on my stove updates automatically. I never realize time has shifted, I'm just left to wonder why I'm so tired / why I woke up so late / etc. until I realize what's going on.
This is basically the only experience that ever makes me feel nervous about how much I depend on technology. I allow my devices to control TIME ITSELF without consulting me.
