My -4's were installed Nov. 2005.
They Calendar out in Nov. 2017.
I will never hit 2,200 hours on them in my case.
Based on what my IA has explained to me, looks like you Calendar out 12 years after install which sounds like Feb. 2017 to me.
This advice may be worth what you paid for it, but I've heard this scenario more than once, and got the same answer over and over.
