So, in looking into this problem we are not seeing an error (when trying to import this data into a timestamp(0) field, I received an "invalid timestamp" error.) when trying import the same data (with the .0 for timestamp) using our Teradata Import Wizard. We also tried using the basic Load option and did not see the error. What are you using to import the timestamp data back into Teradata?
