Breaking News:Facebook Ads Manager now allows "Hourly Breakdown" of campaign performance!To find this new reporting option, simply go into Ads Manager, click "Breakdown", and under “Delivery” you can select the following:

• Time of Day by Ad Account Time Zone: Breaks metrics down by the time of day the ad was served in the ad account's time zone.

The results will then be divided By Hour Of day like you would find in AdWords' Audiences.
