Parent article: File creation times
ctime is actually very useful, as it is currently the only somewhat reliable way to determine that something has changed (by checking whether ctime or mtime has been updated). For some reason when people copy files from other places they like to also copy the last modification time. Fortunately that will set the ctime to the current time and they cannot alter that. So when something breaks and I want to find what changed I can at least search for recent ctime or mtime.
