stop watch in Simulink

Hello,
I have some difficulties with measuring the time between two 'events' (without using the Gauge-blockset). In Simulink I generate random numbers. Each time the output number is over 18 the measurement should be started until the number falls under 18 again.
Does anyone know how to realize it? I'm pretty bad at programming so I thought it's easier to use a triggered subsystem instead but I can't find a way to make it work.
Greetings, Franzi

Compare the number with the constant 18, it will generate pulse signals based on the value.
Feed the signal to an "Integrator" block. Enable the External reset. Use the falling edge to reset the integrator.
