How to multiply a time variable by a boolean?

Hello guys!

I have been trying to multiply time varialbe, in the case a AC voltage, per a boolean, I want to control the time variable to works just when >0. I know I can do that with a diode, however I need to do using a multiplier. I'm usign the block 'Product" but it doesn't accept the Ac voltage, any tips ? maybe I can use a convert block, but i don't know wich one.

It is not possible to connect power lines to Simulink blocks. The circuit you have is incomplete, perhaps you want to use a circuit breaker and other elements to build a meaningful electrical circuit.
