When I click today I get this:
Showing 2009-06-14 to 2009-06-14 ; current time is 2009-06-14 19:12:14 UTC
When I click yesterday I get this:
Showing 2009-06-13 to 2009-06-14 ; current time is 2009-06-14 19:14:44 UTC
So yesterday shows me June 13th (yesterday) and June 14th (today). This doesn't seem right.
