Connect to a NTP server, here is how:
```cpp
#include <NTPClient.h>
2016-04-08 22:34:51 +02:00
// change next line to use with another board/shield
2015-12-08 17:21:16 +01:00
#include <ESP8266WiFi.h>
2016-04-08 22:34:51 +02:00
//#include < WiFi.h > // for WiFi shield
//#include < WiFi101.h > // for WiFi 101 shield or MKR1000
#include <WiFiUdp.h>
2015-12-08 17:21:16 +01:00
const char *ssid = "< SSID > ";
const char *password = "< PASSWORD > ";

WiFiUDP ntpUDP;
2016-04-08 22:34:51 +02:00
2017-07-24 10:09:33 +02:00
// By default 'pool.ntp.org' is used with 60 seconds update interval and
2016-05-14 12:08:45 +02:00
// no offset
2016-04-12 15:35:34 +02:00
NTPClient timeClient(ntpUDP);
2015-12-08 17:21:16 +01:00
// You can specify the time server pool and the offset, (in seconds)
// additionaly you can specify the update interval (in milliseconds).
2016-05-21 21:15:49 +02:00
// NTPClient timeClient(ntpUDP, "europe.pool.ntp.org", 3600, 60000);

## Function documentation
`getEpochTime` returns the unix epoch, which are the seconds elapsed since 00:00:00 UTC on 1 January 1970 (leap seconds are ignored, every day is treated as having 86400 seconds). **Attention** : If you have set a time offset this time offset will be added to your epoch timestamp.
