How to get the resolutiondate in a consistent format: webhook + API

[WindHub Support]

From Webhook, Jira sends the "resolutiondate" as unix-timestamp.

From jira API fetch, the "resolutiondate" comes as datetime.

We would like to get the resolutiondate in a consistent format through both methods.

Is there any way to make the webhook send datetime or to get the API to send Unix-timestamp?
