## Which issue does this PR close? part of https://github.com/apache/arrow-datafusion/issues/8147 ## Rationale for this change The join filters all use the [ExtractEquijoinPredicate](https://docs.rs/datafusion/latest/datafusion/optimizer/extract_equijoin_predicate/struct.ExtractEquijoinPredicate.html) optimizer to make the eq expression the key for the join on, and then the presence of `join on` determines whether to use `HashJoinExec` or `NestedJoinExec`. In this process, `can _hash` function determines whether an expression type can be hashed, but currently this function does not support timestamps with timezone. ## What changes are included in this PR? Modified the `can_hash` function to support timestamps with timezone. ## Are these changes tested? ## Are there any user-facing changes?
