Problem description
API enforces ISO format for time representation like; "Start date time in ISO-8601"
Expected behavior
Datetime must follow RFC, not ISO, as this is defiled in the guidelines:: https://github.com/camaraproject/Commonalities/blob/3ee2c09be6e13983c5566f70c26353a6a3a3cf86/documentation/API-design-guidelines.md#115-data-definitions
