ntp

NTP #
Plugin that allows you to get precise time from Network Time Protocol (NTP).
It implements whole NTP protocol in dart.
This is useful for time-based events since DateTime.now() returns the time of the device.
Users sometimes change their internal clock and using DateTime.now() can give
wrong result. You can just get clock offset [NTP.getNtpTime] and apply it manually
to DateTime.now() object when needed (just add offset as milliseconds duration), or you can get
already formatted [DateTime] object from [NTP.now].
By default lookup address for NTP is: time.google.com
For example on how to use look in github library repository example/ folder.
How it works #
Using int offset from getNtpTime()

default localTime is DateTime.now()
default lookUpAddress is 'time.google.com'
default port is 123

DateTime startDate = new DateTime.now().toLocal();
int offset = await NTP.getNtpOffset(localTime: startDate);
print('NTP DateTime offset align: ${startDate.add(new Duration(milliseconds: offset))}');

Using DateTime from now
DateTime startDate = await NTP.now();
print('NTP DateTime: ${startDate}');
