Well... you can simply shift your time scale. Anyway your xlim is less than the range of t. If Dt is your translation (in your case Dt=2)

Instead of

 plot(t,x);

use

 plot(t-Dt,x);

Otherwise you can do the translation in the argument of your function.

 x=(5/2)*(sign(t+2+Dt)-sign(t-2+Dt));

What's with the pause command at the end of your code?
