Describe the bug
~10 sqllogictest cases are failing in Substrait round-trip mode because of the following error:
query failed: DataFusion error: Substrait error: Field 'ts_nano_eastern' in Substrait schema has a different type (Timestamp(Nanosecond, Some("UTC"))) than the corresponding field in the table schema (Timestamp(Nanosecond, Some("America/New_York")))
To Reproduce
cargo test --test sqllogictests -- --substrait-round-trip date_part.slt:101
Expected behavior
The sqllogictest passes in Substrait round-trip mode
Additional context
This is part of a broader initiative to improve the reliability of Substrait-to-DataFusion logical plan conversions.
