DS1307 SetTime - where is it?

I don’t seem to be able to find this - can anyone shine a light please

Teensy 3.2
32x32 SmartMatrix

MatrixClock example is running, and displaying “Stopped” on the panel.

Comments in the sketch say to run “… the SetTime example…”

It’s one of the examples for the DS1307 library. I’m not in front of a computer, but probably under file->examples
