TimeByDay in SQL Query won't return a value later than 5/31/2013 in Project Server 2010

I'm creating a SQL query that won't return values beyond May 31, 2013.  After some research, I've found the culprit to be the TimeByDay field as shown in the query below.  It returns no values.  As I look at data in Project Pro 2010 and Project Server 2010, there a lots of values that should be returned.  Any ideas what could cause this?

SELECT DISTINCT TimeByDay
FROM         MSP_EpmResourceByDay_UserView
WHERE     (TimeByDay > CONVERT(DATETIME, '2013-05-31 00:00:00', 102))

Thanks in advance for any thoughts.
