It's not necessary to expand the 'time' field of the name. It's not interpreted by userspace, it's just there to prevent collisions when moving directories about. If your cache goes weird in the future because there was a collision with an object that was moved to the graveyard 68 years ago and not cleaned up, then that's probably a bug in cachefilesd.
But I've no objection to using ktime_get_real_seconds() and truncating the value.
