   ### 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
   
   EDIT:
   I have also tried casting the `timestamp` to `timestamptz` in the query, but 
that leads to the mismatch 
   ```
   Received: Timestamp(Nanosecond, Some(\"UTC\"))
   Expected: Timestamp(Nanosecond, Some(\"+00:00\"))
   ```
