How map duckling entity to rasa

duckling returns entity name as dim like time, email etc

but how do u map time from duckling to booking date for my conversation flow?

what if I have multiple entities of the same type, like start date, end date or sender mail, recipient mail, how do I map the entity identified by duckling to my entity.

I am sure there should be a very easy way to map this. but for some reason, the docs don’t have any details about this. any help is much appriciated.
