jorgeulices said Hi, I wonder if someone can help to use the $clock variable, i can set it, but i can´t make the clock run´s in all application, i mean i need to make the classic tick´s of the clock. Thanks.

Can you give some more detail on exactly what you are trying to do? What you have done so far, and what the results have been? I think there are enough people who would like to help out, but you haven't given much of a starting point!
