這件作品是日本設計師佐藤大所創作，作品的外表是一條長16米的塑膠管，但塑膠管的剖面是時鐘，而觀眾能夠因應自己的年齡而把塑膠管切開並帶走切片。每切開一毫米就代表一歲。
作品本身就是與時間相關，佐藤大把「時間」這一個抽象的概念以塑膠管表達出來，此外，觀眾把「時間」切出來後更能把切片打磨、拋光等，讓人們獲得了屬於他們的時間，不過時間是有限的，而這作品則讓觀眾思考如何分配有限的時間，從而令他們更珍惜自己的時間。
This is an installation by the Japanese designer Oki Sato. While it looks like a 16-meter-long plastic pipe in appearance, it serves as a clock when you cut through the middle of it. Each visitor can slice a piece of the tube-like clock according to their age - each millimeter represents a year of age.
Engaging with the subject of time in an innovative way, the designer Oki Sato represents the abstract concept of time with tangible materials like plastic pipes. After slicing a piece of "time" for themselves, people can "own" their time by going through a custom-made process of production stages including polishing, sandblasting, etc. Yet, time is limited. This artwork inspires the audience to contemplate how to distribute their time more efficiently and treasure their own time.
