How to reset time to zero at the change of one value

I have a function, which takes reminder of time from total time set. What I am trying to do is whenever my cyc = 0 at that instant only the input B of function should be changed. Also, at that instant the time t should reset and start from 0.

Can anyone guide me on how should I do it?

Thanks

B = 1;  % usual input B value 
if cyc == 0
    B = 3; % input a different B value when cyc = 0
    y = myFun(B)
    time = 0;
end
function y =  myFun(B)
 % your function code 
end
