This was an old mcdivitt issue I was involved in back in the day, the hardware we were using was on development FW and still is. Will close out if it's still an issue and reproducible on stable hardware then we can work it.

And can be seen from kernel 3.13~4.12 Not sure if this is a bug to the software or the hardware. Test case: sudo /sbin/hwclock --set --date "2/2/80 03:04:00"; sudo LC_ALL=C /sbin/hwclock Expected result: * You should see the clock has been changed to 1980 Actual result: * It's still showing the current time and date. But if you check it again later (about 1 or 2 seconds) with "sudo hwclock", you will see the updated time and date.
