How do I create a timer to be shown?

I want to find out how to create a timer to be displayed after player enters his dd/mm/yyyy in a box and the timer starts displaying the total amount of time in Years/Days/Hours/Minutes/Seconds/Milliseconds continuously at present.

What objects should I be using ?

I've found the timer behavior but it doesn't do this kind of stuff I need.

If could anyone give me a suggestion...

You have betwhen 2 possiblities to choose what is better for you. Chosing a custom plugin is more easily, but insn't official and may cause problems.

It looks so complicated for the beginner of me... I will try to read and understand how things work...
