[Boost-users] sliding window containing n seconds of data

I'm looking for a way to examine an array of object structures for an adjustable window of n seconds. My application reads objects at a high rate (which I'll have to throttle), and I'd then like to put them onto an array. My thinking is to assign a timer on each object that is initialized to n seconds and once the timer expires, the object is removed from the array, but while it's on the array, I'll iterate over the objects looking for the info I need. I put this out on the boost list as I suspect boost has the mechanisms to handle this and someone could suggest a good way of going about it. Any help much appreciated.
