T

Description

This function returns the time elapsed since the start of measuring (in seconds).

Using the time function, time-dependent virtual variables, e.g. sine waves, can be calculated.

Example of a sine wave of 0.5 Hz: sin(2*PI()*0.5*T())

Tip
	The time function can be entered In the expression editor simply by double clicking in other expressions, as is the case with a signal. The two brackets behind T are required for syntax reasons, as in the case of the number Pi.
