[GitHub] [arrow-datafusion] thinkharderdev opened a new issue #2116: ScalarValue serialization loses timezone

[GitBox <gi...@apache.org>]

thinkharderdev opened a new issue #2116:
URL: https://github.com/apache/arrow-datafusion/issues/2116


   **Describe the bug**
   A clear and concise description of what the bug is.
   
   In `datafusion-proto`, `ScalarValue::TimestampX` disregards the optional timezone:
   ```rust
               datafusion::scalar::ScalarValue::TimestampNanosecond(val, _) => {
                   create_proto_scalar(val, PrimitiveScalarType::TimeNanosecond, |s| {
                       Value::TimeNanosecondValue(*s)
                   })
               }
   ```
   As a result, the value will be deserialized to a `ScalarValue::TimestampX(<timestamp>,None)`. 
   
   This will, for one thing, cause binary expression evaluation to fail if one operand is a timestamp literal and the other is a column expression for a column that has a timezone.  
   
   **To Reproduce**
   Steps to reproduce the behavior:
   
   **Expected behavior**
   A clear and concise description of what you expected to happen.
   
   The timestamp should be serialized in the proto message and preserved on deserialization.
