You have to initialize (once, on boot) this to something. I don't really see the point of initializing it to zero and putting the atime/mtime on a few entries back to 1970, when we have the value there already.
We /know/ we have to use the RTC values for things like apm suspend, for instance - I don't want my 'make' to be broken through races with userspace time functions - so if we are prepared to read RTC on resume, we should be prepared to read RTC on boot.
