In dealing with time in an application- sometimes it's extremely straightforward, and sometimes it's a little more complicated than it seems. Take elapsed time, for example. For shorter time frames, we can simply use a timer - but for longer time frames that doesn't always work. And what if we want to know how long a controller has been powered down? We can't use a timer if the controller isn't even powered on to run it.

In this Livestream we will create User Defined Function Blocks (UDFBs) that will take some of these trickier time calculations and solve them with simple solutions.
