Download Include File 

https://github.com/taranais/NTPClient/archive/master.zip
  • Click here to download the NTP Client library. You should have a .zip folder in your Downloads
  • Unzip the .zip folder and you should get NTPClient-master folder
  • Rename your folder from NTPClient-master to NTPClient
  • Move the NTPClient folder to your Arduino IDE installation libraries folder
  • Finally, re-open your Arduino IDE
