hwclock and a bunch of less known porgrams like chrony.
Where the interrupt can be generated its a clear win, otherwise
it might be more reasonable to return EINVAL instead of trying
to emulate it - presumably hwclock can use some fallback method.
Btw the interrupt need not to be hardware, for the Q40 I test
a rtc register once per jiffie and generate a "soft interrupt".
It could be done generic at least for m68k.
