 The functions //getIn()// and //getOut()// return an input or output. To access the signals on those in- or outputs, use //getSignal()//.
+===== Timestamp =====
+Every signal carries a timestamp. The timestamp of a signal is usually set in input blocks. Block which read from an external source and deliver this value on a output signal will set its timestamp to the time of the acquisition of the value. \\
+Most blocks will not alter this timestamp. However, blocks which depend on the sampling time such as integrators or differentiators will change the timestamp according to their inner algorithm.
