A camera recorded one frame every minute (day and night) for two separate three-week periods in autumn and spring. The film is shown on two adjacent screens, each having a soundtrack that was recorded on a sampling basis. The left hand screen was shot at the autumn equinox and the right-hand screen at the spring equinox. The structure of the film is based on the rotation and tilting of the earth as we pass from summer to winter and back. The centre of the film coincides with the equinox and is the point at which day and night are the same length on both the left and the right screen.

伦敦圆拱形建筑千禧巨蛋的出现是新自由主义的权力象征。由1987年拆卸发电厂以兴建千禧巨蛋开始，到1999年的日蚀，及落成后的灯光和烟火表演，影片以缩时拍摄的方式，重点式地记录着它的诞生，暗喻英国当时急欲兴建一座国际性地标的意图。
