Hi,
I'm trying to use this library to get network time in a chat system to avoid to get device date since the user can manually set the date/time on his device.

I'm testing with this example code retrieved from documentation:

ntpClient.getNetworkTime("pool.ntp.org", 123, (error, date) => {
  if (error) {
    console.error(error);
    return;
  }
  console.log(date);
});

While on iOS simulator this works as expected (I haven't tried it on real iOS device yet), on real Android device I'm getting this error on console:

'socket-0', 'bound to address:', '0.0.0.0', 'port:', 0
'socket-0', 'closing'
Invalid Date
'socket-0', 'closed'

What can this error be due to? Notice that I set a manual date/time to test this snippet.

My packages.json:

...
"react": "16.8.6",
"react-native": "0.60.6",
"react-native-clock-sync": "1.1.0-a",
"react-native-ntp-client": "1.0.0",
"react-native-udp": "2.6.1",
...

This is error is showing up with React Native 0.62.2 and react-native-udp 4.0.2.

TypeError: dgram.createSocket is not a function. (In 'dgram.createSocket("udp4")', 'dgram.createSocket' is undefined)

This is located at ntp-client.js:39:21

var client = dgram.createSocket("udp4"),
ntpData = new Buffer(48);

Will appreciate any help on this. This issue has become a blocker for us. Thanks.

Every few requests I'm getting the above error (it's not always 18, though, it can be several other numbers). I have tried with several different NTP servers and I'm still getting this error. Any idea what could be going wrong?

anyone can help me please ?
i don't know what's the problem of my error

this is my code

componentDidMount() {
    ntpClient.getNetworkTime("time.google.com",881, (error, date) => {
        if (error) {
            console.error(error);
            return;
        }

        console.log(date); // Mon Jul 08 2013 21:31:31 GMT+0200 (Paris, Madrid (heure d’été))
    });
}

and in Log show this

Thank you in advance

Hi,

See tradle/react-native-udp#117. Right now we can't contribute to the resolution but we keep an eye on.

Thanks
