`import 'package:ntp/ntp.dart';

Future main() async {

'time.google.com',
'time.facebook.com',
'time.euro.apple.com',
'pool.ntp.org',
].forEach(_checkTime);
}

Future _checkTime(String lookupAddress) async {
DateTime _myTime;
DateTime _ntpTime;

/// Or you could get NTP current (It will call DateTime.now() and add NTP offset to it)
_myTime = DateTime.now();

/// Or get NTP offset (in milliseconds) and add it yourself
final int offset = await NTP.getNtpOffset(localTime: _myTime, lookUpAddress: lookupAddress);
_ntpTime = _myTime.add(Duration(milliseconds: offset));

print('\n==== $lookupAddress ====');
print('My time: $_myTime');
print('NTP time: $_ntpTime');
print('Difference: ${_myTime.difference(_ntpTime).inMilliseconds}ms');
return;
