Do I have the right to change flights when the airline have changed the time?

I booked flights for the summer and my return flight has changed time, and is now earlier. There's a stop over, which would now be a very long wait due to the first flight being earlier. Will I be allowed to change the second flight to a earlier one, so I don't have to wait so long?
Also who do I change this with if I do, the company I bought the tickets from or the airline itself?

Will private air traffic control in the airline industry mean more planes will crash
