MKR1000 WiFi RTC Compiling Error

Hi all I'm trying to get the tutorial 'Wifi RTC' to run and I am running into compilation errors. I've literally copy/pasted the tutorial code into the sketch changing only ssid, password, and time zone.
I've done quite a bit of searching but nothing seems to solve anything.
The errors are below:

There must be something simple?

Hi, do you have the latest version of RTCZero and SAMDCore?

Can you please update your IDE to latest version? 1.8.1 contains a lot of bugfixes!

Thanks a_guadalupi for your reply, I've updated the IDE and the board, still getting the same message.

Any ideas where I should look to troubleshoot some more? I've really exhausted all avenues.

Thanks!!

Can you please post here your sketch and verbose build log?
