I didn’t know about this. I’m hoping it is a non-event. I worry about the GPS equipment in my airplane. Particularly since the age of the device seems to be a factor. https://sanfrancisco.cbslocal.com/2019/04/02/gps-week-rollover-event-devices-systems/

Devices at highest risk for failure include the older devices or the devices that have not been frequently updated. Y2K marketing driven panic...they hope. I personally am more concerned by these big brother, "self-empowered" , possibly too powerful, government employees that I found on the same link: Rights?

Look for me on Twitter, Instagram, Facebook or Tic Toc...or anywhere you may frequent, besides SimHq, on the Global Scam Net. Aka, the internet. I am not there, never have been or ever will be, but the fruitless search may be more gratifying then the "content" you might otherwise be exposed to.

Sorry.
Back on track, still sounds like "the sky is falling"/"Y2K again" marketing to me.
Luckily, have my bag of cat bones, my secret horn full of runes and, in a pinch, street signs to get me where I wanna go.

It's a bit overblown. And Nixer, some of us are still using landmarks for aerial navigation.

Also, Y2K was real. Smug remarks that it was a hyped up are somewhat disingenious; things would have gone south rather quickly had it not been for the massive effort of countless IT professionals to fix the problems before they occurred. Just sayin'. For us civilians outside of the IT world, it was terribly over-hyped. Everything from the water in the taps to clouds in the sky were to stop working thanks to Y2K and an ever-competitive 24 hour news cycle. But thanks to a bunch of old gummers with their somewhat rusty but easily remembered FORTRAN skills that were brought back as contractors, disaster was avoided.

I thought it was COBOL that saved the day. That and monochrome monitor's.

How does that quote from PT Barnum go again?
Hmmm...I wonder...

There are lots of things that can go wrong... as a simple example a string concatenated from individual table cells, then later parsed by another program, or routine assuming fixed length strings.
201904050202 is a representation of the date when I wrote this text... now if it was back in 1999 represented in 2 digit format as 9912312359, and then ticked over by adding 1 to the year... 10001010000
Which is year 10, a month which doesn't have a value, on the 10th, at midnight, - and all other data following is also off by one position. It is an easy fix - check the date field is 4 digit, or make sure it knows that it rolls from 99 to 00, and that the code knows this is *after* 99... even when doing date sorting by text field etc...
Definitely a ton of places where *some* ways of doing things can cause problems.
You don't even *understand* the problem as you demonstrate it's absence by using 1999 and 2000 to prove the issue is a nothing-burger, when this is the *solution* to the problem of 00 being less than 99 and 100 not fitting into two digit fixed length ascii fields.

QED I think. Again, the older “legacy” systems we were told were going to crash the entire world, worked as noted in binary or hex, not decimal or ASCII as described here. Am old enough to remember working with them in machine code. But signing off now. Not going to bother getting involved in futile debate.
