Wowza Record Stop after time n

How can we recognize this function? For example, we have 3 vars where saving time in hours. Example: 3 hours in the first var. Ok It tells wowza that after starting wowza burns stop this line after 3 hours! Not break up! Just stop. Or maybe wowza has 1 param where we can write the time by default, then wowza will be sending “stop recording” for all the streams that were started?
