andre-cc-natzka opened a new issue, #4311:
URL: https://github.com/apache/arrow-datafusion/issues/4311

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   At the moment DataFusion supports type coercion for (`DataType::Time`, `DataType::Utf8`) and (`DataType::Date`, `DataType::Utf8`) pairs, but does not account for type coercion for (`DataType::Timestamp`, `DataType::Utf8`).
   
   **Describe the solution you'd like**
   We need to add support for type coercion for a (`DataType::Timestamp(_, _)`, `DataType::Utf8`) pair (all time units considered) into a `DataType::Timestamp(TimeUnit::Nanosecond, _)`. The reason why the output type has to consider nanosecond accuracy is the fact that this is the only time unit supported by Arrow.
   
   **Describe alternatives you've considered**
   
   
   **Additional context**
