something like:

void main() {
      if (sensor<black){
            startTimer();
      }
      if (sensor == white && timerStarted == true){
                if (timerValue<12600){
                        doSomething();
                }
                if (timerValue>12600){
                         doSomethingElse();
                }
         }
 }

PM me if you need anything else

Dubios you pretty much got it in terms for C++, just in a not very psuedoy pseudo code. For C++'s elif it's just

if(somethinghappens){
	dosomething;
}else if(Somethingelsehappens){
	dosomeotherthing;
}

Does the same thing as your elif, but just not as fancy or short
