Overview

Returns the / RFC822 representation of a time.

Imagine this HTML structure:

YAML usage example:

selectors:
  description:
    selector: span
    post_process:
      name: 'parse_time'
      time_zone: 'Europe/Berlin'

Would return:

"Tue, 02 Jul 2019 00:00:00 +0200"

It uses ‘Time.parse`.
