For the time.h example (timeGPS)
When complied. Error "time_t" does not name a type
In the sketch the line is:
time_t prevDisplay = 0;
#include <time.h> is still black. It doesn't seem to have the library installed.
I can't find that example in the library you point to! Also, remove the old library (move it to another location) as 2 libraries with similar names can cause issues.
