README

        

This is my NTP library for Arduino. Please note the examples used are written 

for a WeMos D1 which uses an ESP8266 for the processor. YMMV. 

General usage is: 

WifiNTP ntp;

ntp.begin();

ntp.time();

This will, if you're connected to wifi, get UTC from time server(s).

Methods: 

	ntp.begin()	- Basic init of functions, use default servers.

	

	ntp.begin(long tzadjust) - Initialize functions and set the timezone adjustment, in seconds. Use default servers.

	

	ntp.begin(char ** ntpServers) - Init functions with null terminated array of pointers to time

	

	servers in dotted quad notation. A max of 4 will be used in round robin.

	

	ntp.time(tzadjust) - Return time, adjusting for timezone seconds. Use -1 or void for no adjustment. 

	

	

Please note the actual UDP NTP Code I used is by  [Michael Margolis](http://www.gv.com/team/michael-margolis/) and  [Tom Igoe](http://www.tigoe.net) in the Arduino WiFi library. That code states it is public domain. Thanks, guys!
