Clock

The clock holds the current iteration number and time. By default the model starts at iteration number 0 and time 0

clock = Clock(0.0, 0)

Clock{Float64}: time = 0.000 s, iteration = 0

but can be modified if you wish to start the model clock at some other time. If you want iteration 0 to correspond to $t = 3600$ seconds, then you can construct

clock = Clock(3600.0, 0)

Clock{Float64}: time = 1.000 hr, iteration = 0

and pass it to the model.
