How can I remove files based on the time they were created?

view story

http://stackoverflow.com – I was copying a directory, and I ended up spitting out its contents in a shared, home directory. I want to delete all these files. They all were "created" in the shared directory at the same time, so how can I filter these files out? Going one by one is not feasible. How would I remove them all in one command using rm command with some sort of "time created" parameter on Ubuntu? (HowTos)
