When I look at the bandwidth usage history graphs, there is one graph point per unit (e.g., one per hour for the hourly graph).
What is the time interval for the data point?
I.e., if the x axis point is 10:00 (as below) and the y axis value is 3828 MB, does that represent a usage of 3828 MB for the period ending on, centered or or starting with 10:00?
I.e., 3828 MB for 9-10? For 9:30-10:30? For 10-11? Or for some other period?
