title: What time zone is the Facebook Ads Insights API's date_start and date_stop sent in?
body: <p>Facebook's Ads Insights API returns <code>date_start</code> and <code>date_stop</code> but since they're date objects I can't tell what time zone was used to demarcate the dates. Is it using Facebook's API timezone which they've mentioned to be PT (UTC -8) or is it according to the AdAccount's time zone as I've found mentions of the account's time zone in the Ads Insights API documentation.</p>
