EasyNTPClient

Arduino library to read time from Network Time Protocol (NTP) servers.

Features

• Handles all heavy lifting involved with managing connections to and parsing time from an NTP server.
• As easy as providing a UDP object to the constructor during initialization.
• Works on Arduino and ESP8266.

Examples

1. No frills

EasyNTPClient(UDP &udp)

Parameters:
    udp: Reference to an UDP object.
Returns:
    EasyNTPClient object.

2. Custom server pool

EasyNTPClient(UDP& udp, const char* serverPool)

Parameters:
    udp: Reference to an UDP object.
	serverPool: NTP server pool. Default = "pool.ntp.org"
Returns:
    EasyNTPClient object.

3. Time offset

EasyNTPClient(UDP& udp, const char* serverPool, int offset);

Parameters:
    udp: Reference to an UDP object.
	serverPool: NTP server pool domain name. Default = "pool.ntp.org"
	offset: Difference from UTC in seconds. Default = 0
Returns:
    EasyNTPClient object.
