Not really. Using the RTC or HPET devices directly is necessary only
if the kernel does not use them for timers. Nowadays, kernels do, and
applications use the proper timer APIs.
You'd need this only if you're using some audio application that
hasn't been updated for many years.
Ok, that explains why it's been a long time since I've seen those device
permissions actually break anything. The reason I ask though is because
the web site for Muse still has a section on making sure /dev/rtc is
accessible:
