Original line:
if (now.hour >= 7 && now.hour <= 19); //If time is between 7am and 7pm print day time setting)
I think it should look like this:
if (now.hour() >= 7 && now.hour() <= 19) //If time is between 7am and 7pm print day time setting)
Notice that new.hour() is a function that returns the hour, and the semicolon would have terminated the 'if' statement.
