How to time three events

Projects Programming
2

I want to record the time when was A, B and C occurred.

unsigned long aEventTime, bEventTime, cEventTime;

void loop()
{
   // Get IR code
   if(code == A) // Whatever that means
      aEventTime = millis();
   // Repeat for B and C.

   // Now, determining which event time is greater than 0 but smaller than the other two is easy
}
