RFA is a 'content agnostic' API - it will deliver whatever fields it receives from the data source.
If you can see the fields CF_DATE, CF_TIME etc for a particular instrument in Eikon for a realtime quote, then you should also see the same fields for that instrument when you subscribe to it using RFA from the same service name.
However, if you refer to the RDMFieldDictionary file that comes with your RFA developer kit, you will note that these fields are labelled as DESKTOP USE ONLY. Consolidated FIDs
This indicates that these fields are only available in Eikon. Please see this post for more details
I recommend you contact our Content Helpdesk for further help. Please create a Product and Content type ticket, selecting 'I cannot find content I am looking for' and 'Thomson Reuters Elektron Real-Time' as the product.
