import PubNubVue from 'pubnub-vue';

const pubnub = PubNubVue.getInstance();

pubnub.time(function(status, response) {
    if (status.error) {
        // handle error if something went wrong based on the status object
    } else {
        console.log(response.timetoken);
    }
});

Response

//Example of status
{
    error: false,
    operation: 'PNTimeOperation',
    statusCode: 200

    console.log(timetoken);
}).catch((error) => {
    console.log(error);
});

Example above show how to create notification payload which APNS will try to redeliver few times (if devices not active) and give up after 10 seconds since moment when it has been scheduled.

Additionally this invitation notification will be grouped along with other invitation notifications (using provided collapse_id as group identifier) and shown as one in notification center.

Returns

Configured and ready to use NotificationsPayload instance.
