Workflow HTTP Request Headers Variables

I have a process that needs to interact with the Duo Admin API
The Duo Admin API expect a Header containing a datetimestamp in RFC2822 format (ie 01 Jun 2016 14:31:46 -0700)

In the workflow engine, the Headers of a HTTP Request Action, are there a set of variables they can accept? ie $rfc2822timestamp

Workflows doesn’t have a way to get the current time yet, but this is something that is being worked on. I will pass along your specific use case regarding RFC2822 so our product team knows that is one of the formats we may need to support.
