Message ack events timestamps always the same

[caiokawasaki]

Reproduction steps

Steps to reproduce the behavior:

1. Send a message
2. Wait for ack events

Expected behavior/Relevant code

I sent a message to a number, I noticed that the ack events are always coming with the same timestamp, is this correct?

Here are some events of the same message that were performed 1 minute apart:

Ack 1:

const messageAck = {
  mediaKey: undefined,
  id: {
    fromMe: true,
    remote: 'xxxxx@c.us',
    id: 'MESSAGE_ID',
    _serialized: 'true_xxxxx@c.us_MESSAGE_ID'
  },
  ack: 1,
  hasMedia: false,
  body: 'Como você está 3?',
  type: 'chat',
  timestamp: 1642104555,
  from: 'yyyyy@c.us',
  to: 'xxxxx@c.us',
  author: undefined,
  deviceType: 'android',
  isForwarded: false,
  forwardingScore: 0,
  isStatus: false,
  isStarred: false,
  broadcast: undefined,
  fromMe: true,
  hasQuotedMsg: false,
  location: undefined,
  vCards: [],
  inviteV4: undefined,
  mentionedIds: [],
  orderId: undefined,
  token: undefined,
  links: []
}

Ack 2:

const messageAck = {
  mediaKey: undefined,
  id: {
    fromMe: true,
    remote: 'xxxxx@c.us',
    id: 'MESSAGE_ID',
    _serialized: 'true_xxxxx@c.us_MESSAGE_ID'
  },
  ack: 2,
  hasMedia: false,
  body: 'Como você está 3?',
  type: 'chat',
  timestamp: 1642104555,
  from: 'yyyyy@c.us',
  to: 'xxxxx@c.us',
  author: undefined,
  deviceType: 'android',
  isForwarded: false,
  forwardingScore: 0,
  isStatus: false,
  isStarred: false,
  broadcast: undefined,
  fromMe: true,
  hasQuotedMsg: false,
  location: undefined,
  vCards: [],
  inviteV4: undefined,
  mentionedIds: [],
  orderId: undefined,
  token: undefined,
  links: []
}

Ack 3:

const messageAck = {
  mediaKey: undefined,
  id: {
    fromMe: true,
    remote: 'xxxxx@c.us',
    id: 'MESSAGE_ID',
    _serialized: 'true_xxxxx@c.us_MESSAGE_ID'
  },
  ack: 3,
  hasMedia: false,
  body: 'Como você está 3?',
  type: 'chat',
  timestamp: 1642104555,
  from: 'yyyyy@c.us',
  to: 'xxxxx@c.us',
  author: undefined,
  deviceType: 'android',
  isForwarded: false,
  forwardingScore: 0,
  isStatus: false,
  isStarred: false,
  broadcast: undefined,
  fromMe: true,
  hasQuotedMsg: false,
  location: undefined,
  vCards: [],
  inviteV4: undefined,
  mentionedIds: [],
  orderId: undefined,
  token: undefined,
  links: []
}

Shouldn't the timestamp of the events be different? It seems that for both acks I'm getting the timestamp of the message and not the event itself.

I got the status timestamps using the following method:

const ACK_DEVICE = 2
const ACK_READ = 3
const ACK_PLAYED = 4

const resolveStatusTimestamp = async message => {
    const info = await message.getInfo()

    switch (message.ack) {
        case ACK_DEVICE:
            return info['delivery'][0].t
        case ACK_READ:
            return info['read'][0].t
        case ACK_PLAYED:
            return info['played'][0].t
        default:
            return null
    }
}
