How to Format Data?

Just signed up to Draftbit a few days ago and have been testing the API integration. Have successfully managed to bring data into my app and bind it to a list, but one of the properties is a date type. The API, returns this property as a timestamp.
How can I format this to an appropriate date format e.g. DD/MM/YYYY?
I have looked at the documentation, but cant find anything related to formatting.
