I'd like to build a clock that makes shifting to daylight savings time unnecessary by instead gaining or losing a bit of time each day as appropriate for the season so that when the second Sunday in March and first Sunday in November roll around it's already in sync. Setting aside the logistics of making this work from a societial point of view, how would you do it technically? Something like leap seconds or leap minutes? Or smaller changes on a more constant interval? [more inside]

Travelling across a time zone by air is ambiguous. It's hard to tell exactly when it happens. When travelling across time zones by air, when does the time change? Especially across multiple zones. I've noticed that I never see or hear a reference to the time while onboard. For instance, a movie might start at "fifteen minutes after takeoff," but not at 4:45pm. [more inside]
