New Relic Deployment

Hello,

I have been using this module for several years now, to record a deployment in New Relic
https://github.com/ansible/ansible/blob/devel/lib/ansible/modules/monitoring/newrelic_deployment.py

I now see on the New Relic website that a variable called ‘timestamp’ can now be used to record the date/time in the past. Which is very useful.
See this as an example https://docs.newrelic.com/docs/apm/new-relic-apm/maintenance/record-monitor-deployments#api.

curl -X POST "https://api.newrelic.com/v2/applications//deployments.json" \
     -H "X-Api-Key:" \
     -i \
     -H "Content-Type: application/json" \
     -d \
'{
  "deployment": {
    "revision": "",
    "changelog": "",
    "description": "",
    "user": "",
    "timestamp": ""
  }
}' 

however, after editing the below file to include the timestamp variable and then run my Ansible Playbook, the timestamp in New Relic is the current date/time (13th January) the API POSTed the request, even though the timestamp variable was for January 1st 2020.
