### Describe the usage question you have. Please include as many useful
details as possible.
Hello,
I'm trying to implement a prepared statement that has a timestamp parameter.
I have prepared statements working with strings, but with timestamps I'm
getting a schema mismatch error.
I'm using v14.
The query for the prepared statement is `SELECT * FROM x where name = $1 AND
$2 <= timestamp`.
I have no problems with the first parameter.
I'm building the second parameter using the type
`arrow.FixedWidthTypes.Timestamp_ns`.
I've tried passing a `time.Time` as the value and it failed. Then I tried an
`arrow.Timestamp` but that also failed with the same error.
The error I'm getting is:
```Parameter schema does not equal Placeholder schema. (...)
Received: (...) Field {name: \"$2\", data_type: Timestamp(Nanosecond,
Some(\"UTC\")), nullable: true, dict_id: 0, dict_is_ordered: false, metadata:
{} }
Expected: (...)Field { name: \"$2\", data_type: Timestamp(Nanosecond, None),
nullable: true, dict_id: 0, dict_is_ordered: false, metadata: {} }```
I would like to know what's the best way to overcome this timezone
difference in the schemas.
Thank you
