While that's relatively worse, it's still a non-issue - just look at your phone if you want the current time. Nobody buys a car for its accurate timekeeping abilities.

I understand that customers are rightfully pissed off that they paid for a clock and no longer have a working clock, but the cost of said clock can't have been more than a few dollars so it still doesn't really matter.

In my head this would suck a lot more if the time was needed to enable more connectivity i.e. syncing calendars, remote start/unlock, etc. But if that was the case these systems would use NTP and avoid this whole mess entirely.
