Time dilation question

I am convinced that time does not dilate. At near light speed an object gains m and shortens in the direction of motion, the increase in m and the foreshortening reduces space required for particle motion, motion slows for the particles within the moving object. If you subject a clock to such a speed, the moving parts gain m and increased inertia, the power supply, however, remains the same, the moving parts will slow and the clock will show time lost, nothing has been lost other the speed of the moving parts of the clock.
