9'oclock (my time is not your time) pertains to a series consisting of three numbers: 5, 10 and 11 works were made for the exhibition "Signs and messages from modern life" at the Kate McGarry Gallery in 2007. The notion of time is a recurring theme in Tobias Rehberger's work. We can recall the exhibition 'Night Shift' at the Palais de Tokyo ( Paris) in 2002 where the works could be seen only from the angle of the sun, exploring the relationship between day, night, and other natural cycles like the sun and moon, life and death. But in 9'oclock (my time is not your time), time becomes a pattern. The artist manipulates the number nine by printing it on three stacked glass plates. Depending on the position and the viewer's eye, the shape evolves to deconstruct the meaning completely. This work is characteristic of artist's practice in the way in which he borrows 70s design (in the refinement of its production, its appearance, and color), and the issue of perception, of deconstruction, and transformation.
