# ntp-client [](http://travis-ci.org/moonpyk/node-ntp-client)
|
||||
|
||||
Pure Javascript implementation of the NTP Client Protocol
|
||||
|
||||
## Getting Started
|
||||
Install the module with: `npm install ntp-client`
|
||||
|
||||
```javascript
|
||||
var ntpClient = require('ntp-client');
|
||||
|
||||
ntpClient.getNetworkTime("pool.ntp.org", 123, function(err, date) {
|
||||
if(err) {
|
||||
console.error(err);
|
||||
return;
|
||||
}
|
||||
|
||||
console.log("Current time : ");
|
||||
console.log(date); // Mon Jul 08 2013 21:31:31 GMT+0200 (Paris, Madrid (heure d’été))
|
||||
});
