OT but since there seems to be multiple Subaru owners — if you are experiencing an issue with the clock on MFD(the small display on top of the dashboard) being too fast, probably depends on models but the causes are,
1) that there’s no CAN bus messages in Subaru cars that offer GPS time, and
2) that at least older models of MFD counts time by dividing 125kHz CAN bus crystal, where a sane choice would be to use 32.768kHz one.
It’s not just your car, the issue is in design. To hypothetically fix it a firmware hack would need to be built. I learned this when a friend of mine told his is always way too fast and often makes him upset for a moment that he might be late to work — don’t know he meant it justify flooring it but sounded like he was genuinely annoyed.
