The network process disk cache uses the creation time to compute a worth value used to determine the order in which cached resources are deleted when the cache is shrunk. In some operating systems like Linux there's no st_birthtime in struct stat, but since cache files are always created and deleted by us, we could use a custom xattr to store and retrieve the creation time of cached resources.
