I was in my neighbour's car (3 Year old Toyota Corolla Hybrid) and they said something like - watch the clock lose 1 hour going over this bridge.

The bridge in question was the Auckland Upper Harbour Bridge and we were going from Greenhithe to Hobsonville.

The screen was on the Map screen, with the time in the top left-hand corner.

Sure enough, the clock went back one hour, somewhere over the bridge and came back to the right time after we had completely crossed the bridge.

I couldn't believe it.

They didn't say it happened on all bridges, and I forgot to ask.

Did a quick internet search but didn't see anything which related to this.

the car must be sensitive to the time-space continuum and you've found a gap! 🤣

some toyotas have the option to set the clock to GPS, with the corresponding offset (time zone) user-configured accordingly. wonder if there's something transmitting on the said bridge that the car picks up???

Cell tower with the wrong time set?

I had thought of that. Emailed Ncuti Gatwa and waiting to hear back (when he's back in the UK).

Better that time is wibbly wobbly than the bridge.

Delete cookies?! Are you insane?!

Does the time go back one hour all year round or just during summertime?

My guess is it's a map error and the vehicle no longer thinks it is in New Zealand, so it's not applying our DST rules.

I would expect the map details in cars to be a very rough outline rather than a precisely plotting our coastline (not that it's in international waters), but if the lines on the 'map' were to not quite meet (or possibly cross), it could create a spot which isn't within the map coordinates.

Pre retirement my job was to go round all the cell towers and check the pendulums on the GPS Caesium clocks. I can assure you they are all set set correctly, I still have my box of pendulum weights if anyone needs to reset a Caesium clock.

Bridge and route were opened in 2017, so guessing the GPS map is out of date and it “gets lost” for a few seconds.

It's a three year old car, so I doubt the maps are pre-2017! If that is the case though, Toyota has some 'splainin to do...

People often mistake me for an adult because of my age.

Keep calm, and carry on posting.

True, but when I look at Google and Apple Maps there continue to be plenty of errors/out of date stuff, and per above if that led to the person “travelling over water” I can see that being a reasonable software bug.

Seems like the most reasonable explanation.

The maps could be old. I have the same car but haven't used the stock maps since installing AA Carplay.
I've no idea how they even get updated. OTA or dealer SD card?
I think on the latest Corolla (still the same shape) the Toyota maps are no longer stock and are a paid subscription

If a car produced in 2022-2023 has navigation maps from 2017 or older installed as default, that's simply not good enough. I'd be surprised if Toyota is that slack, but who knows. Tardy updates after purchase is expected (they're all pretty hopeless in that regard)...

I presume it's a bit like a CD player, a bit defunct.

Somehow, I am missing the point of some of the posts. I don't mind being enlightened.

The screen showed an 'interactive' map (perhaps the correct name is Satnav, but I haven't looked).

The screen showed a time. The time changed and then changed back.

The correct time was 11:05 am. I had just been to a funeral which started at 10:30 am (a short one). The time went back to 10:05. My neighbour warned me that this could happen.

Is it/could it be linked to the Satnav?

Personally, based upon my limited knowledge, once the time in my car (Kia Sportage, 2018) is set, then it is fixed.

Apart from my initial post, I have no more information (unless I go and talk to my neighbour, which I will not be doing as they have no interest in cars or even satnav).

I could drive my car to the same bridge but am not going to waste the petrol.
