sql &= "FROM Trn_DC_All "
sql &= " WHERE (Content LIKE '% PAGE%') AND Convert(datetime,Substring(Right(Trn_DC_All.Content,21),2,10),7) >= " &

View 5 RepliesI am very surprised to see the output of the function with the given value ,DateTime.Parse("08/19/2011 11:32"). I am using VS2008. Always it returns 08/19/2011 11:32 AM. and if the pass value would be 08/19/2011 14:23 then the output value would be 08/19/2011 02:23 PM. But sometimes it is returning 08/19/2011 11:32 PM for DateTime.Parse("08/19/2011 11:32"). Why?
