T.R.E. is an acronym in Domesday Book for the three Latin words tempore Regis Edwardi, 'in the time of King Edward', or 'before 1066' in the Phillimore translation.

The draft circuit return for the south-western counties, the satellite known as the Exeter Domesday, or Liber Exoniensis, originally rendered this as 'on the day on which King Edward was alive and dead' (5 January 1066).
