Timezone math sucks. You know how it goes. Someone says "4pm my time", and now you're counting on your fingers, opening a converter in another tab, and getting it wrong by an hour anyway because one of you moved the clocks last weekend. ZoneGlider puts your cities where they actually are on the planet, and lets you drag the daylight across them. Move it forward and 4pm Wednesday in Brisbane becomes 11pm Tuesday in Los Angeles, so you read the answer off the screen instead of working it out. DRAGGING TIME AROUND Drag anywhere on the screen. A screen width is twelve hours. Push it gently and it creeps along; throw it and it covers days, because the gearing follows your hand rather than the other way round. WHO'S AWAKE, WITHOUT GUESSING Every city gets a 24-hour track on one shared axis, so the rows line up instead of each telling its own private story. Flip to the Availability lens and those tracks turn into flat bands: awake, and asleep. You set your hours and theirs. "Can I call them right now" becomes a colour instead of a calculation, which is the entire point.
