Timekeeping gets a short animated survey here, tracing the tools people built to track the hours before clocks existed and the devices that replaced them. The film moves in broad strokes from early methods of marking time's passage through to modern instruments, using animation rather than archival footage or interviews to carry the history. It stays brief and general, more an illustrated overview than a deep account of any single invention or era, and works best as a starting point for the subject rather than a detailed record of it.
