While using system Identification app, we get the time plot and model output, transient response plots etc. In all these plots the x-axis is time. what is the unit of time there?

I understand you are not sure of the units of time on the x-axis. While creating data, the default units of time is seconds. However, this can be modified by changing the TimeUnit property. Please refer to page 2-50 of the below PDF
