I was trying to make the RTC work in my photon as i did with my arduino, them i realize that the
#include <WidgetRTC.h> wasn’t working because there is no such file in the lib.
I updated to the lasted version from github https://github.com/vshymanskyy/blynk-library-spark. but it still missing:
Did i import the wrong thing or it’s like that for the photon?
