title: BigQuery ignoring --use_avro_logical_types flag while loading data with AVRO format
body: <p>I have AVRO data with following fields where created_at &amp; updated_at is a TIMESTAMP column which is represented in AVRO Logical Type that converted it into LONG.</p>
  
  <p>AVRO Schema:</p>
  
  <pre><code> |-- id: integer (nullable = true)
   |-- account_manager_id: integer (nullable = true)
   |-- total_sales_existing_accounts: integer (nullable = true)
   |-- total_sales_new_accounts: integer (nullable = true)
   |-- qtr_start_date: long (nullable = true)
   |-- qtr_end_date: long (nullable = true)
   |-- created_at: long (nullable = true)
   |-- updated_at: long (nullable = true)
   |-- total_sales_with_contact: integer (nullable = true)
   |-- total_sales: integer (nullable = true)
   |-- total_sales_percentage_compared_to_previous: integer (nullable = true)
  </code></pre>
  
  <p>So, while loading this file to BigQuery I want the BigQuery table should have TIMESTAMP column and not INTEGER column having UNIX EPOC TIMESTAMP.</p>
  
  <p>As per the BigQuery documentation, I am setting <code>--use_avro_logical_types</code> this flag to <code>True</code> while loading data.</p>
  
  <pre><code>bq --location=US load --source_format=AVRO --use_avro_logical_types=True writable.test_account_stat gs://test-bucket/production/avro/account_quarter_sales_stats/*.avro 
  </code></pre>
  
  <p><a href="https://cloud.google.com/bigquery/docs/loading-data-cloud-storage-avro#logical_types" rel="nofollow noreferrer">Documentation</a></p>
  
  <p>But the <code>--use_avro_logical_types=True</code> is ignored and my BigQuery table is having these date columns as INTEGER.</p>
  
  <p>I tried with API as well as command line as per the following documentation but no luck :(</p>
