@adamhooper thank you for the perspectives. I see the challenges with adding
a second argument to `to_timestamp` and would love to consider other
alternatives.
Can you suggest a strategy for the usecase described in this ticket, namely
"writing a query using SQL against data stored in parquet that has an explicit
timezone?"
In other words, how do you suggest supporting the following query?
```sql
SELECT ...
FROM my_parquet_file_where_timestamp_col_has_a_specified_timezone
WHERE timestamp_col > to_timestamp("2021-06-21T12:00Z")
```
Which currently fails because the arrow type of `to_timestamp` has `None` as
the timezone, but the type of of `timestamp_col` has a specific timezone?
