When scheduling a price change, the date changes from what I entered

In iTunesConnect, I am trying to schedule a price change to tier 1 for one of our apps for the duration of a month, but whatever dates I enter as the start and end dates, when I press "save", both dates change to one day before what I selected.


So I'm entering September 4th as the start date. and October 3rd as the end date. I press "done"... the dates are correct. Then when I press "save", the start date changes to September 3rd and the end data changes to Octover 2nd.


What's going on with that? Is there some crazy logic that I'm missing, or is this a bug?


Thanks!
