This is the correct data type to convert UNIX/Epoch timestamps to a date. If you built a report before changing the date type in the Architect, those existing reports will not get the new data type automatically. In this case you will need to edit the field formula and switch it to UDT manually or just remove and re-add the field. Any new reports should use the new data type. If this is not the case please contact support with your version of Yurbi as there is currently no known issue with the UDT data type.
