Ok, so I turned it on. And as expected it's deeply underwhelming. But you learn where I used to live in London!

Thanks for all your support. I took Lucie out to dinner to thank her for sacrificing part of our holiday so I could film a video. But which I mean: WE took Lucie out for dinner. She said thanks!

John here, I sat in my garden at 2AM (CET) to catch the rollover. I've had four different make and models of pre 2007 GPS but not event full, none gave the wrong data/time. The tom-tom did not give me a date either. A friend of mine gave me a Bluetooth GPS yesterday. (used for old PDA systems) It says it's 2099. This makes sense as the '20' is likely static. We will not have the year 3k in a long time. Catching the rollover is just two lines of code. And can be costly is missed... As forsatNAV there are many more systems in orbit at this moment, just to be less reliant on USA. Lastly I've been working on a device that needs the exact time with a maximum error of 100 ppb on a day. (9ms a day). It uses the reverse GPS. I tell it where it is exactly and will give me the exact time. Here is the list of all data formatting bugs from the past and the future: The CNAV rollover is not in there yet. <a href="https://en.wikipedia.org/wiki/Time_formatting_and_storage_bugs" rel="nofollow noopener" target="_blank">https://en.wikipedia.org/wiki/Time_formatting_and_storage_bugs</a> Also a cool doc from the USA government on GPS and the rollover: <a href="https://www.gps.gov/governance/advisory/meetings/2017-11/powers.pdf" rel="nofollow noopener" target="_blank">https://www.gps.gov/governance/advisory/meetings/2017-11/powers.pdf</a>

I logged into Patreon and became a patron of yours for this video. It was just as mundane as I thought it would be. I will continue to give you financial support if it means more unnecessary content like this in the future.

Matt Parker

Thanks! I can promise more videos and absolutely no increase in whelming.

Even though I've been paying my $1.11 for years, I never check here. Please do mention on youtube whenever you have patreon-locked content.

I have never commented on any of your mind blowing content before. Therefore I will leave a comment on the most Parker Squarish video I have ever beholden: Team Tau

Matt Parker

I did consider setting up a camera to get the exact moment… but there is only so much I can do while on holidays. (But to be fair: the rollover was planned well before my vacation was.) That’s a great story about 2099. The list is great as well.

Matt Parker

Thanks for your support! I try to add something on Patreon at least once every two videos on average. I don’t want to point I out too often as I know a lot of people cannot afford it. But thanks so much to those of you who can!

Matt Parker

I respect and appreciate your comment if not your choice of circle constant team.

Did you say you "used to" work at Queen Mary University? When did that end?

Change Preferences and scroll WAAAY to the right until you get to Change time and date... I was literally screaming hard and loud in hopes of it reaching back in time.. but alas. my time flux capacitor had died on me. ;)

I finally did it, I came out of the closet and became a lover of Matt. I'll await the disappointed photo's each month. Wanted to give a shout out to you for the awesome and clever video's you continue to produce, thank you.

This is the stuff I pay for. Six minutes of you turning on an old satnav system... No, seriously, this IS the stuff I pay for. Keep it coming ;p

I suspect if you were to retry this now it would no longer work. My tomtom of a similar vintage ceased to lock last saturday (I have heard rumour that some manufacturers have adjusted to use a different epoch, maybe theirs is out by 1 week).

I do hope Lucie felt as if she were in the sky ... with diamonds.
