Looks like we have one coming up in June.

How exciting.

I wonder if that will fix the tear in the time-space continuum in my shop??

Leap seconds can be a real hassle with a pendulum clock.

Well time flies when you are having fun.

Is it mandatory? I'm not much of a jumper anymore.

Oh man! I was just getting caught up on my sleep from springing ahead!

Yes - does that mean one more or one less second of sleep

Leap ahead, Pat. :)

Ugh... they're probably going to want us to change our clocks at 2 in the morning, aren't they...

There's no cure for that.
It requires a sacrifice.

I recommend Ensign Crusher.

Does he still have his red shirt?

Well it went so swimmingly well the last couple of times... I'm just suuuure there will be no problems

This is a fun summary of fail the last time around, mostly in java apps. We can (perhaps vainly) hope that people are handling it a bit better this round. Overall on par with y2k for visible outages, probably because of poorer preparedness.

these two are perhaps overly nerdly :D

I'm counting on this to return my hair and my ability to reach the floor without the currently requisite grunt.

Good recommendation.

But if the USS Voyager shows up, Seven of Nine is definitely staying.

I've been streaming Voyager via Netflix for several weeks now...almost done. I'm naming any new daughters, Seven. :D

YOu are gonna regret that, starting at about age 15................. ;)

So you want hoardes of pubescent teens lusting after her?! Bad idea :p

Let me know when it happens so I can leap over it.
Give me plenty of time, these old legs don't leap like they use to.

First daylight saving time, and now this.

I work in IT and don't recall any issues the last time there was a leap second. I don't think I even knew it was happening the last time. We do keep our servers up to date so maybe that is why no problems.

It depends on what you had running if you had a problem... and likely many folks who did have a problem probably didn't notice it because they weren't sensitive to the specific time issues or attributed the issues to solar flares and rebooted the machines (likely happened for many of the high cpu load problems).

I don't remember having a problem either, but then I work on wholly uninteresting things so there's that :D

A bunch of java code running on specific linux kernels was hit:
http://wiki.r1soft.com/display/kb3/High+CPU+Usage+on+CDP+Server+caused+by+Linux+Kerne l+Leap+Second+Bug
and there were some other issues as well: http://winningraceconditions.blogspot.com/2012/07/linuxs-leap-second-deadlocks.html

In practice this is a hard problem to test because it happens rarely so keeping updates up to date may or may not actually help you. There has been some discussion of actually abolishing the leap second: http://catless.ncl.ac.uk/Risks/25.50.html#subj1.1

It turns out that "keeping time" is hard (even if you are a programming musician) and keeping time when it leaps hither and yon is even harder.

There's a bunch more out there if you feel as amused by this sort of thing as I am - risks digest is usually pretty good and a few google searches on "distributed locking time leap" and "distributed systems time leap" are insightful.

There is of course a solution - simply bombard the earth with asteroids to keep it from slowing down so much:
https://what-if.xkcd.com/26/
there may be some side effects not everyone would approve of :D

and John, don't get me started on daylight savings: http://www.timeanddate.com/time/dst/history.html sheeeesssh.. I miss living in HI and AZ for more than just the weather.

You'd like IN, too, Ryan. :D

Not since about '05 or '06--that's when we went on DST with the rest of the sleep-deprived, zombie idiots. :D

No foolin'?! I lived in Chicago but regularly worked throughout IN in the late 80s to early 90s. IN was the worse because it was only parts of the state that changed.

That's a shame! More people should come over to the "dark side" :P

Wow daylight savings and time zones in general are/were a mess in Indiana: http://www.timeanddate.com/time/us/indiana-time.html Not that a lot of states are any better (thinking AZ with the navajo vs the rest of the state on different times depending on the time of the year). Time is complicated!

It's still a little bit of a mess because most of the state is in the Eastern Time Zone, but the NW and SW corners are in the Central Time Zone. My in-laws live just over an hour away (straight north of us), yet are in a different time zone.

When we made the switch to DST, it actually cost me MORE. Previously, darkness came early enough that the upstairs of our then-house cooled off just enough that putting the kids to bed wasn't too bad in the summer. After the switch to DST, I had to install a window A/C unit to make it possible for anyone to sleep up there.

We need to STOP THE INSANITY!! DST, how do I hate thee? Let me count the ways...
