Hi all,
I'm in the process of testing out the Events API V2 integration with my PagerDuty instance, and am having trouble making use of the `payload.timestamp` field of the Alert Event endpoint.
Specifically, when I am including the `timestamp` field in the request, I can't find it reflected anywhere in the alert that is created in PagerDuty. For example, I used a simplified version of the example payload given on the documentation page for sending an alert (https://developer.pagerduty.com/docs/send-alert-event):
```
{
 "payload": {
  "summary": "Example alert on host1.example.com",
  "timestamp": "2015-07-17T08:42:58.315+0000",
  "source": "monitoringtool:cloudvendor:central-region-dc-01:852559987:cluster/api-stats-prod-003",
  "severity": "info",
  "component": "postgres",
  "group": "prod-datapipe",
  "class": "deploy",
  "custom_details": {
   "ping time": "1500ms",
   "load avg": 0.75
  }
 },
 "routing_key": "samplekeyhere",
 "dedup_key": "samplekeyhere",
 "event_action": "trigger"
}
```
However, after successfully creating an alert from this webhook payload, I could not find where the `timestamp` field is stored. I checked the following locations:
* The 'Incidents' page shows the 'Created' field as the time at which the PagerDuty instance received the event, not the time in the provided timestamp.
* Inspecting the alert itself, the other fields (severity, summary, custom details) are shown but not the timestamp.
* Clicking the 'View Message' key led me to the 'Event Details' page which also did not include the timestamp field.
Is there something I'm missing, for example:
* There was something wrong with the timestamp I used? I did try using other timestamps that conform with the ISO 8601 format.
* The timestamp is not used anymore?
* Something else about the payload I used is incorrect?
Thanks in advance.
