title: Facebook Marketing API, retrieving ad hourly_stats_aggregated_by_advertiser_time_zone analytics in the past
body: <p>I'm build historical database for facebook adaccount analytics.</p>
  
  <p>In our query, we set breakdown to 'hourly_stats_aggregated_by_advertiser_time_zone' and aggregate insights later.</p>
  
  <p>Problem is some ads in the past seem not support this breakdown and return empty so i just want to know from which time in the past this breakdown can be applied?</p>
  
  <p>Thanks</p>
