@destinationstransfers/ntp v2.0.0

NTP Client

Lightweight (no dependencies) modern Javascript (Node 8 LTS or later) implementation of the NTP Client Protocol. Based on node-ntp-client and NTPServer.

We use it in production at https://transfers.do for webhooks timestamps checking (like Stripe and so on) where VM time is not reliable enough.

Usage

Add the module to your project with npm install @destinationstransfers/ntp.

const NTPClient = require('@destinationstransfers/ntp)';

const date = await NTPClient.getNetworkTime();
console.log(date) // 2017-09-20T15:29:09.443Z

API

getNetworkTime accepts hash of parameters, below they are with default values:

const { getNetworkTime } = require('@destinationstransfers/ntp)';

const date = await getNetworkTime({
  timeout = 10000, // timeout in ms, default is 10sec
  server = 'time.google.com', // ntp server address
  port = 123, // NTP server port
})

You also can override default values using env variables NPT_PORT, NTP_SERVER and NTP_REPLY_TIMEOUT.
