Your wording is confusing.
Do you mean you want:
(a) All records starting 10 months before the end of the current month.
(So today is September 1st, the end of this month is September 30th. 10 months back from that is November 30th, 2012. So you want all records from November 30, 2012, until now.)
(b) All records between 10 months back from today and one month after today.
(So 10 months back from today is November 1, 2012. On month after today is October 1, 2013. So you want all records from November 1, 2012, to October 1, 2013.
Which of those do you mean? If you don't mean either one, then give an *EXAMPLE* of what you mean, using today as a starting point.
An optimist sees the glass as half full.
A pessimist sees the glass as half empty.
A realist drinks it no matter how much there is.
