I just installed several new HDDs in a machine and I happened to notice one of them had two errors reported, so I ran smartctl -x on it and got this:

As you can see, the drive's power-on hours are 520 (which is accurate, as I've had it for under a month), but the two errors say they occurred at 10610 hours and 16878 hours — obviously impossible.
What's happening here? Are the errors real? Worrisome? Could there be some kind of "odometer tampering" going on here by my vendor?
Update
(I would have had this much earlier, but HGST Western Digital :/ is really unhelpful (why do they give OEM drives serial numbers if they're not going to keep any info about them at all?), and slow to respond too.)
When I'd installed these, I had noticed that they didn't have the manufacture dates on the labels like my old ones had, but I just chalked that up to the maker not printing them any more and thought nothing more of it… till I saw Deltik's great answer. It hadn't occurred to me these would (or could effectively) be erased.
After my attempts to get official word from the manufacturer ('s new owner) failed, I pulled them all and sicced my flatbed scanner on 'em, at max settings. By doing the old zoom-and-enhance, I was able to spot evidence of each one having been erased. Here's one of the easier-to-read examples:

Reduced, redacted .jpg overview:
Original resolution cropped .png of the scene of the crime (the upper-right corner of the label):
The more eagle-eyed of you can probably already read it, but here's a rectangle of auto-levels:
So, yeah. All the drives have subtle markings remaining from this deliberate attempt to defraud, and they're all from March/April/May of 2015. Not quite what "new" means at the end of November 2018.
Additionally, as some of the other commenters are, I'm pretty shocked that SMART can be subverted like this. Isn't most of the point of it gone if it can be reset?
I'll be pursuing this further, believe you me. Watch this space.
