We would expect this column to be inferred as a TimestampType column. `typeSoFar` will be `Timestamp` when `inferField` is called on the second entry which is `DateType`. We need logic in `inferField` to try and parse `DateType` even when `typeSoFar` is `Timestamp` -- This is an automated message from the Apache Git Service.
