Need help in implementing IOT Touch Screen thermostat

Hi arduino community,
I am new to arduino forum and trying to figure out the errors getting in one of the project. I am implementing IOT Touchscrren Thermostat
ESP8266 WiFi touch screen thermostat.

After placing libraries and code, i am getting several errors. Most of them are from DS1302RTC and timezone libraries. I am getting following errors upon compiling

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
Arduino: 1.0.6 (Windows 7), Board: "Arduino Mega 2560 or Mega ADK"

any help will be greatly appreciated. Thanks

any help will be greatly appreciated.

You want us to explain the errors in code you didn't post? Sorry, my crystal ball is at the cleaners.
