NINA_NTPClient_Advanced.ino

/****************************************************************************************************************************
  NINA_NTPClient_Advanced.ino

  For AVR, ESP8266/ESP32, SAMD21/SAMD51, nRF52, STM32, SAM DUE, WT32_ETH01, RTL8720DN boards using 
  a) Ethernet W5x00, ENC28J60, LAN8742A
  b) WiFiNINA
  c) ESP8266/ESP32 WiFi
  d) ESP8266/ESP32-AT-command WiFi
  e) WT32_ETH01 (ESP32 + LAN8720)
  f) RTL8720DN

  Based on and modified from Arduino NTPClient Library (/~https://github.com/arduino-libraries/NTPClient)
  to support other boards such as ESP8266/ESP32, SAMD21, SAMD51, Adafruit's nRF52 boards, SAM DUE, RTL8720DN, etc.
  and Ethernet/WiFi/WiFiNINA shields
