Postman current timestamp for UTC as ISO 8601

I wanted to know: How can I get the current timestamp for UTC in ISO 8601 format to appear in the body data of a Postman request?

After reading some of the Postman documentation and online comments, this is the solution (using Postman v5.0.1 for Chrome 58.0.3029.110 on macOS 10.12.5) I used:

  1. In the Builder, while editing a request, click the "Pre-request Script" heading below the URL field.

  2. In the editor field that appears, enter this single line of JavaScript:

    postman.setGlobalVariable('timestampUtcIso8601', (new Date()).toISOString());

  1. Clarify and agree on the scope of the system

    • Who is going to use it?
    • How are they going to use it?
