@oristarA,
I've heard that kind of thing expressed in so many ways, I hesitate to comment.
My
preference would be to say Resolution 'eleven - fifteen.
I have also heard 'eleven hundred - fifteen'.
I have also heard 'Resolution one - one- one - five'.
I think you can pretty much pick whatever sounds good to you. Kind of like giving time as 4:15, quarter past four, or 1615 if you are using a 24 hour clock.
