NTP Clock example

[BaltasarParreira]

This line of code on the NTP Clock example doesn't do nothing:

const bool HOUR_12 = true; // 12-hour format

This is a possible missing code (in bold) so this works:

byte format_hour(byte hr){
if (HOUR_12) {
if(hr > 12){
hr-=12;
}
if(hr == 0){
hr = 12;
}
}
return hr;
}

Also this example is a bit different from the one showing on your YouTube video (https://www.youtube.com/watch?v=FwXqQos0ZFk).
Can you share the one from the video and also the color changing android APP?
