But they didn't have issues between Earth and Mars time.

Fine, you win.

Ehhh, I agree with you. There can be issues, as you pointed out. But they can be dealt with, as I pointed out. So it's the same answer as "why is Bob Dole smiling?"
Depends.

I hear the NASA people and the martians got along really well.
It's a shame the martians expected pounds-seconds instead of newton-seconds. Or was it the other way around?

Oh, you're mis-understanding the facts.

@flabdablet said:given the constraint that sunrise must always happen at 06:00:00 everywhere.
I have more objections, but you need more hour digits. After all, the poles will need to be able to track up to 4380 o'clock. :-)

You left out the twilight periods (though civil, nautical, or astronomical changes how long of a twilight you should be dropping) which reduce how long the sun is up.
-
I think sunrise wouldn't literally mean "the sun goes over the horizon", or you would need to know a place's topography to be able to tell when the sunrise is (imagine a place near a mountain). If you refer to sunrise as the time when the projection of the sun on the surface of the Earth crosses a certain longitude west of your current longitude (90° should do it), however, you fix that slight issue.

time.windows.com is always broken. I have Windows servers that can't sync with Microsoft because they are 10 seconds ahead. No issue with nist ever.
With my previous install of 7, every time it updated by NTP, the time went off by hours (usually a regular interval, but sometimes it was totally bizarre). I disabled NTP, and it worked great until an update... then it broke regularly again. Re-enabled NTP, and it was perfect again. And, of course, no problems with this install, and there is no difference in the programs I have installed. Well, unless some random game on Steam was the culprit.
Windows uses UTC internally as well. And saying Linux is somehow better at handling DST... well, it isn't. Unless you tell it to set the hardware clock to UTC, it'll still set it to local time. Just like Windows. And OS X. And [insert OS name here].
I'm tri-booting Windows 8, Ubuntu, and Android on one machine. I'll have to boot into all three on Sunday and see what happens to the system clock. Also... have to resist the urge to add another OS...
Linux uses UTC system clock by default, except when initially installed next to a windows installation.
On my desktop, Windows 7 and Ubuntu are both using UTC; Windows was installed first, and as far as I can remember, I didn't choose any special time settings.
My laptop dual-boots Windows 8 and Ubuntu, and as far as I can tell, both are using UTC also. Then again, I can also count the number of times I've booted Windows on it, and they're also on separate drives... which I doubt means much, but OSes are wonky.
Times are not dates, and dates are not times, despite the fact that a date and a time and a timezone can be bundled together as a timestamp represented as a single number.
I'm working on a small web program that needs to store a day-month couplet, and had to explain why I also store the year and make the user specify the year to another dev. Since the front end presents the user with a click-to-select calendar, it's hardly a burden on them, but I was amazed I had to explain it at all.
ah but that's the thing, we cannot differentiate the occurence times between events that occur "less than" one unit of plank time apart. as best we can figure out/calculate the plank time is the smallest possible unit of time there is because quantum physics.
It may be more accurate to say that no events occur at smaller intervals.
Here's a brain teaser for you: the square of the planck length is known as the planck area, and Bekenstein showed that this is the increase in the area of the horizon of a black hole when it absorbs 1 bit of information. So, let's compute the change in radius.
ΔA = λ² [I'm using lambda for planck length just because it stands out.]
4πR² - 4πr² = λ²
4π(R² - r²) = λ²
To avoid lots of nonsensical wrangling, we can assume r is zero.
4πR² = λ²
R² = λ² / (4π)
R = λ / (2√π)
IE, the radius of a spherical horizon upon absorbing 1 bit increases by less than the planck length. Huh?
i thought quantum physics was weird shit?
QM is pretty straightforward, actually; blame Bohr. The copenhagen interpretation that most people are taught discards realism when QM is non-local, not non-real.
-

Don't believe so. Spec says sunrise must always happen at 06:00:00; doesn't say that every 06:00:00 must be a sunrise.

Only tangentially related but I'm gonna leave this here since it's a pretty picture

So ... Red means that 12:00:00 is
afterbefore astronomical noon?EDIT: Corrected
-
where does Taco Standard Time fall into all of this?
-
Other way around, no? It gets more red further west, where astronomical noon is later than time noon; the further west you get, the more ahead time noon gets (until the next TZ boundary).
-
You're right.
All this timey-wimey stuff makes my head fa-spin.
-
-

Given that the spherical horizon in question belongs to a black hole, you're going to have to work pretty hard to convince me that the radius (as opposed to the area) has any physical meaning.
-
So ... Red means that 12:00:00 is
afterbefore astronomical noon?Red means that the location is west of the timezone's meridian, that astronomical noon is later than “timezone” noon, and green means that the location is east. (Along the meridians, you've got white.) Ignoring DST, of course.
Russia appears to be TRWTF, even worse than Spain. The great red peril still lives!
-
And you could also say that Alaska is
behind the times.

China could be worse. 1 timezone, based on Beijing solar noon. Get's pretty bad in the westernmost portions.
I'm surprised Russia is so red. I would have expected them to want to be as close to Moscow time as was reasonable, which would favor green.
-
And you could also say that Alaska is behind the times.
Part of the reason it is set up that way is where Juneau is in the state.

I really should get started on that Dicsourse to NNTP gateway thing I've been thinking about lately...

It's a brain teaser, not a quiz. You can handwave the radius away if you like; it's your brain.
VaelynPhi:

Yes, actually. The mathematical wrangling is this:
The radius of a sphere, as a function of its surface area, is:
R = (1/(2√π)) * √A = k√A
So a change in area by a produces this change in radius:
ΔR = k( √(a + A) - √A )
Treat the rightmost expression as a function of A, holding a constant; as A increases, this function decreases. So, for larger black holes, the increase in radius with the addition of a certain area is even smaller.

Now there is a WTF of epic proportions! I approve.Things are set in motion already: see http://what.thedailywtf.com/t/im-doing-a-discourse-api-now-on-github-throw-me-the-features-you-want-also-random-ramblings-thread/4469?u=offbyone
I actually really want to do this. I much prefer my trusty NNTP-client to the fustercluck that is this Ember.js frontend.

I always liked trn better. It had a pretty little treeview.
I've tried
trntoo, when I was figuring out which newsreader I wanted to settle on. I don't remember why I choseslrnin the end.
Nowadays I usemuttwith the nntp-patch. That gives me a nice treeview too and I don't think any of the other newsreaders can do things thatmuttcan't.I also sometimes use Thunderbird when I'm in a graphical environment.

The last time I actually used Usenet I bought a copy of Agent, which was pretty nice for 1996 or whatever.

That wasn't what I was trying to do. I wanted to link to a different topic. Went to that topic, right-click on a random time-ago-stamp, "Copy Link Location", "Paste" in the reply box, remove
/<postnum>?u=offbyonefrom the end because I wanted to link to the topic in general instead of a specific post.
Post my reply and see that there is no link in the right gutter next to my reply.Went to the topic I wanted to link again, left-clicked on the time-ago-stamp of the OP, copied the URL it provided, pasted that in my edited reply, post the edit and tadaa! the link in the right gutter appeared.
The only difference between my first and second attempt is the
?u=offbyoneparameter, as far as I can tell.All that extra work did get me the First Share badge though :)

Strange. I can try to repro if you'd like.

Ah - think I know what it is, if it's what I just saw..
Previous post didn't have a gutter link when I posted. Refreshing the page brought it in though.

That might have been it. I didn't have to refresh after adding my userref to the URL for the gutter link to appear though.

If you want a system to test your code on to see how badly it breaks on backward time steps, Windows is for you.
Don't do this to a Domain Controller unless you have several days set aside for cleanup. Backwards or forwards.
Had a tech do this to me once by two days forwards - led to a very long night.
I miss the days of Novell Netware when you simply declared a new epoch and was done with the problem.
-
i did break out those adjustments into a common place that's self encapsulated so when (and it is when) they decide to change their mind i only have to update all those date time rules in one place.
Sanity escape clause! I like it!

We just had a trouble ticket submitted to change the time on a PBX system (that is basically a modified Asterisk system that they bought from another company) because the on-site person who usually does so is out on vacation this week. How do you fuck up a system so badly that twice a year you have to go in and set the time on a PBX instead of just pulling system time?
-
Wait... Do you mean you had to change the time somewhere in Asterisk configuration? How the fuck do you set Asterisk up so it doesn't use the system time in the first place?
No, wait, don't tell me, I don't want to know...
-
I sent someone to do it, so I have no freaking idea. I have never even looked at that system. I was as blown away as you are when the ticket came in though.
-
I can say for sure that not having the time zone on the server auto-update is Doing It Wrong -- the first step in the setup documentation is installing and configuring NTP.
Depending on the phone end points, the most likely "actual problem" here is that the phones aren't auto DST. Cisco SPA phones are whiny little bitches about it, such that you have to 1) have a working NTP connection and 2) add a fairly fugly configuration line either via provisioning or manual config to define your DST rule. Either one without the other is insufficient, and will cause you to "have to" update the
clocktime zone on the phones twice a year.

“Burn it with Firefox”? Well…
-
Is that before or after "FourthMeal"? IE, "Disgusting encouragement for obesity time".
No, it's from a show that I guess that you don't watch.
-
It gets really screwy when you need to change the timezone twice a week, or even every couple of days - for example, on a cruise liner.
I have yet to find a good solution.
So far the least insane option has been to set everything to UTC and have two NTP servers - one that's static and used for 'real' times, and the other jumps an hour at 2am on request.Unfortunately that's crap, because it takes quite a long time to propagate across all the thousand IP phones and hundred-or-so of other devices that need to show "local" ship time - and worse, confuses the heck out of some of them, because time really did leap backwards.
It'd be really great if there were some way to broadcast a change to the current local timezone across a subnetwork, but I've never heard of any way to make an IP phone do that.
-
I was wrong about the system. It was a Comdial PBX system. FTWTFW (for the WTF win), it does not reference system time at all. You have to sign in to an admin voicemail, through the handset, hit a key combination and then key in the time in 24-hr format. This is for an end user to do.
