Neither. There is no such thing as "creation" time (on Unices anyway). -C gives you days since last inode change. Typically, you use -M, which is days since last modification of the file contents. > I need a way to delete files based on the file creation time > and that time needs to be static. No can do, since file creation time isn't kept anywhere.
