Well, you didn't answer my question which is why do you need UIE and

you want because it is in sync with your system time.
We set up `chrony` to use UI events as a time reference. Upon startup,
`chrony` opens the RTC with UIE_ON, reads the initial RTC value on the
first transition, then keeps the system clock in sync with the RTC using
the interrupt signal. So we want to synchronize the system time to UIE,
not the other way around.

I was genuinely asking, because I couldn't find the original letter,
only subsequent ones from 2-4 years ago, removing bits and pieces from
individual RTC device drivers.
