Problem with MicroViewDemo - would not compile
The 4th line in void setup()
“setTime(10,10,01,17,1,2014);”
gives the following error
“ ‘setTime’ was not declared in this scope “

How do I modify the sketch to make it work?

Hello having exact same problem ... Time library is there but sketch won't compile.
The learn.microview.io server link dead.



Error is:

OK so for Arduino IDE 1.8.2 on Macintosh (if that matters) solution is:
Get new Time library from Github (or get the entire Teensy thing from https://www.pjrc.com/teensy/td_libs_Time.html )
The Github link is https://github.com/PaulStoffregen/Time
I got the zip Time-master.zip and it became Time-master folder.
The Time library version appears to be 1.5
Replaced contents of Documents/Arduino/libraries/Time with contents of Time-master
In MicroViewDemo replaced #include <Time.h> with #include <TimeLib.h>

This solution also works for MicroViewAnalogClock. Used an external editor to make permanent change to the example code (the Time.h to TimeLib.h mod).
