This is, quite frankly, an idiotic argument.  Userspace doesn't access
the RTC, the kernel does, and if the underlying implementation is broken
it doesn't matter if it is accessed one time or a thousand.  For the
record, in most cases the RTC gets accessed about every 15 minutes to
update the time based on network time.
