UK Date Format with Timestamps

I'm using the timestamp option in several databases which is fine for the backend data.
However I'm in the UK as as always Xataface defaults to the US date/time format.
How can I switch my timestamp fields to display UK date and time such as dd/mm/yyyy hh:mm:ss
Would a change affect filtering and sorting?
