The planned addition of a “Leap Second” this June may disrupt the Internet and satellite navigation systems.

Interesting

To me it sounds like the hullabaloo we had when we went from 1999 to 2000.
Nothing happened then!

Tom Scott explains a very complex issue in a short video that is easily understood.

Thanks for the link.

Another one that has peaked my interest here in the US is the actual location of the Four Corners Monument. That is the point where the state boundaries of Arizona, Colorado, Utah and New Mexico meet on the Colorado Plateau.

I have seen reports on the net that the actual surveyed monument is misplaced by as much as 2.5 Miles! A survey in 2009 by the National Geodedic Survey claims it is 1807 feet east of the monumented location.

It would be interesting to see what a handheld GPSr would read if placed on top of the monument.

This happens every couple years. Nothing happened all those other times.

I believe Dr. Who & the Time Lords will fix this problem, if indeed it's worth worrying about.

Long live the "Tardis"

Well, I think I'll just take a "Wait and See". I'm not going to worry about something as small as a second when there are lots more things going on in the world.

Will check back in July...

TARDIS you mean. It's an acronym.

millennium bug day is 2079 2080
there was never going to be a problem in 1999 2000
the default date is 1980 and it has a 2 digit year counter adding time to 1/1/1980
IF there are any still running in 2079 they will only be in museums

There was quite a bit of problems but primarily minor. A lot of mechanical devices using electronic controllers were affected as their programs were burned into read only memory (firmware) that used an entered time/date. Many of those were "fixed" until they could be replaced by resetting the clock back to a date when the days matched. I don't remember the year, but it was in the 80's if I remember correctly. Elevators, small private telephone systems and a lot of voice mail systems had to have circuit boards replaced as just a couple of examples. The real date in that mess was Sept. 9, 1999. 9/9/99 was used as a test entry in a lot of programs and some would go into debug mode where they stopped operating when that date rolled around. Those were some of the first systems fixed.

Some Time Nuts, myself included, will be sitting by our GPS-disciplined clocks watching and recording... I've got a recording from a couple of summers ago, the last leap second, with the seconds display going 56 57 58 59 60 00...

And everything else keeps on ticking. The dogs don't even bother to get up.

there have been 25 of these in my lifetime. And I don't really feel 25 seconds younger (or older, depending on how you look at it)

LOL!!!!!

does that mean I have enough time for another beer?

No, it actually means the bar will be closing a second earlier than you thought it would.

It's somehow surprising. This change is some sort of maintenance change, so it probably will be no problem. But who will read this article than? It will be challenge for time sensitive applications (like banks or stock exchanges) but most people will see no difference. Unless some problems with Facebook or Twitter will kill you instantly.

WHAT!! We're beyond 1999??? Great Scott, what will we do now... I've not yet acquired my flux capacitor capable of generating 1.21 gigawats!!!!! What will I ever do??

The second is being added to the atomic clock in Greenwich and will have zero effect on any system. Sorry, doomsayers, but life will go on as normal.

And if it ends, it ends... nothing we can do about it!

Just give me a second....

Not really...

Your computers already deal with shifts of plus or minus an hour twice a year (daylight savings time -- unless you're in Arizona?), and nothing bad happens.

An added second isn't going to make waves. Nor should it whip up a frenzy from folks trying to figure out how to make a buck off the event.

Those of us around here who are more rational (or is that jaundiced and cynical) can use this as a calibration cycle to let the whackos identify themselves so that we may give their future pronouncements the appropriate weight and consideration...

Amen!

Maybe if it's one of the newer doctors. The old ones were pretty incompetent and lame.

6 month supply of dry food and water, oh wait a minute, I'll do like I did in Y2K! Find out who has the stores and good stuff and takes theirs if the world collapses, lol

I liked some of the old doctors, not sure about the new one yet.

Ninja Gear and Crackerjack whistle ring...just in case

Then I'll plan on getting up the next day.

The manufacturer I worked for had a TOY for an option. The TOY or Time of Year module would adjust the clock automatically for daylight savings time. If you didn't have a TOY, you had to reset the clock manually.

If you are 'snowed-in' or relaxing on a beach, read "Longitude" by Dava Sobel. It also explains the more important topic of John Harrisons' building of a 'clock' that was unaffected by the motion of a rolling ship.

For example...did you know that in the late 1700's and early 1800's it was someones prime (get it?) responsibility to destroy the 'clock' if boarded by the enemy? Without accurate time you could not accurately navigate.

Off topic, but interesting.

Oh, K6RTM, you are so wise... Will be watching for the wackos.

I wonder if Arizona will not participate in the leap second either?

So I don't have to tinfoil my house????

How much do I worry? I haven't worn a watch on my wrist since retiring in 2003.

But just in case our wall clock should handle that without a hiccup when it synchronizes at night with the atomic clock in Boulder CO.

than sorry!
