BUT the "time" library in the RAR is out of date (2014), and won't work with Arduino 1.6.6 or later, so you need to get the 1.5 version here: https://github.com/PaulStoffregen/Time/releases

Hi again roddyp

Just a side note:
If you do a file compare (using ExamDiff) between the "time" library supplied on the WeatherDuino Pro2 package and the "newer", you will see that there isn't any changes on the code. In the "newer", just  the time_t type assignment to some Constants was removed.

Also, the new time.h calls timeLib.h, so we can still use on the code the statement #include <time.h>

But as said before, there is no need to upgrade the library, the included time library, is working perfectly.
The problem is the arduino IDE 1.8.0

Thank you for your patience, investigation and help pointing the problem with the new IDE 1.8.0.
