### Is your feature request related to a problem or challenge? `arrow/benches/cast_kernels.rs` currently benchmarks casts to UTF-8 from `Int64`, `Float32`, and `Float64`, and casts from UTF-8 to date types, but it does not benchmark casts from temporal types to UTF-8. As a result, performance changes to the Date, Time, and Timestamp formatting paths are not visible in the cast kernel benchmark suite. ### Describe the solution you'd like Add representative benchmarks for: - `Date32` to `Utf8` - `Time64(Microsecond)` to `Utf8` - `Timestamp(Microsecond, None)` to `Utf8` - `Timestamp(Microsecond, timezone)` to `Utf8` These cases represent Date, Time, Timestamp without timezone, and Timestamp with timezone formatting. There is no need to benchmark every time unit. Use the same input size for these cases, with enough values to produce a stable signal, and report throughput alongside iteration time. ### Describe alternatives you've considered -- This is an automated message from the Apache Git Service.
