Why would they play with the time zones for this in Canada

http://www.space.com/spacewatch/annu...se_030523.html

want canada to set there clocks 1 day in advance, or atleast 16 hours in advance, I dont get it

Nobody wants anybody to change any clocks.

What are you looking at?

We have always had the Int'l Date Line...this eclipse will be visible to people on both side sides of the line, so it will be on different days at the same time, so to speak. That is what is meant by " local clocks will be set to the previous day: Friday May 30."

I think I will now stop taking you seriously.

You not only don't get it, you don't have a [expletive] clue.
1) This the Planet X forum. This question should be on the General astronomy forum.
2) Do you have the slightest grasp of the concept of time zones? :-? The eclipse occurs at 4:12 AM GMT (Greenwich Mean Time) Saturday, May 31st. For the Mountain time zone of northern Canada, this is 11:12PM Friday, May 30th. For the Pacific time zone of northern Canada, this is 10:12PM Friday, May 30th.

Edit to add:

Second that

I got confused, I guess my dyslexia is acting up again, sorry folks, I swear it was not done on purpose

Its not just this post. All of your posts seem to assume that some shadowy "they" have an ulterior adgenda. Quit automatically assuming that somebody is trying pull a "fast one" if you don't understand something at first.

Explain that to me, please!

Did you even read the website?

Text say´s: "since the Moon’s penumbral shadow falls to the east of the International Date Line, local clocks will be set to the previous day: Friday, May 30."

So this text clearly says that this "happening" (eclipse) is a reason to recalibrate the clock´s.

No it doesn't.

However, adding to the oddities associated with this eclipse, for these "Al-Can localities," since the Moon’s penumbral shadow falls to the east of the International Date Line, local clocks will be set to the previous day: Friday, May 30. Moreover, for these particular locations the eclipse will be occurring not at sunrise, but around the time of sunset.

Figure it out yourself!
1)It's summer time (actually late spring).
2) That means that the sun sets very late in the far north (later in the summer it will not set at all - ever hear of "the land of the midnight sun? :-? ).
3) The eclipse occurs late at night in northwestern Canada.

Therefore: The eclipse occurs at sunset in northwestern Canada. DUH!!!!!

OK. Lets try this again. The clocks will not be "set" as in adjusted. The clocks will be showing a time and a date from the previous day.

Example:

It is 1 am May 23rd on the East coast of the US.
At the same time it is 10 pm May 22nd On the West coast

Perhaps the use of the word set is confusing.

Not sure what you mean by 'play with the time zones'. I didn't get that from the article. There was several mentions of the eclipse being in diffrent 'time zones'. Perhaps you are refering to this: Except when it's midnight at the dateline, there's always two diffrent days on the earth. As each hour goes by the new day grows around the earth following the timeline that contains midnight. In practiclal terms, when it's Saturday 1:00 AM here in Austin Texas - it's still Friday 11PM where my brother lives in California. Note how in Russia the eclipse is in the morning but in Alaska it's in the evening.
What I find odd is this statement:
Anybody have an explination for that?

They mean that the clocks will read the previous day, not that they need to be moved back.

You really don't have a [expletive] [expletive] clue!

Get this straight!! The eclipse occurs early morning 5/31 GMT. This is late evening in northwest Canada. Nobody is changing any clocks.

Changing a clock would not alter the time of day the eclipse was visible to someone! If I were going to see it at sunset, I'd still see it at sunset regardless of what I do to my clock.

Clocks do not control the movements of celestial bodies!

Um, guys?

Can I just step in here and say that I for one don't think Skywatcher is just trolling? I get the sense of someone who's confused by all this astronomy stuff that's been flooding the Web lately, both the "good" astronomy and the "bad" astronomy (thank you SO much, Nancy Lieder, for raising astronomy's Internet profile :roll: ), but who just doesn't know the right questions to ask. I suspect that he's been listening in on the various Zetatalk chat sessions, and to folks like Samsara, and suddenly it's like there's this whole new world called "Astronomy" out there that he never paid much attention to, but suddenly it seems like it might be really important to "understand this astronomy stuff", since Nancy Lieder and Samsara & Co. seem to think "this astronomy stuff" is going to lead to the destruction of Planet Earth any day now.

So could we cut him some slack, 'kay? And give him the benefit of the doubt? And just focus on giving him some factual answers to his questions? I admit, it's hard to tell what he's getting at sometimes, but maybe just assume that his overall interest lies in "having this astronomy stuff explained".

So, in this case, he wants to have an "annular solar eclipse" explained, and in particular, I think he wants to have this explained, from the article.To someone who doesn't understand "this astronomy stuff", this does sound like they're saying that folks in Canada will have to set their clocks back, or ahead, 16 hours or something. And I'll bet a nickel that somewhere on the Web, there's some PX conspiracy theorist claiming that this means that NASA and the government are making everybody in Canada re-set their clocks so as to cover up the loss of time due to the Earth's rotation slowing, blah blah blah...well, y'all know the drill.

And truth to tell, I'm not sure myself what they're getting at, either, although that could just be because I haven't had any coffee yet this morning... Aren't they just saying that if you live in Al-Can and ya wanna make sure you see the eclipse, you should set your clock so as to correspond to the Universal/Greenwich time of the eclipse, 'cause that whole International Date Line time thing is a real b*tch to figure out...

On one side of this timline, in Canada, the eclipse will be seen at sunRISE and on the otherside of this timline the people there will see the eclipse at sunSET...... Now how far apart is the timeline between eachother, can one be sunrise and the other sunset...

FYI, the dateline doesn't run through Canada.

The time line (the International Date Line) is not located in Canada. The International Date Line is located in the middle of the Pacific Ocean.

He's trolling, or he lied about being 21 years old, or he's never been to any school.

Skywatcher: That is quite possible, depending on how far north you are. If you get yourself an astronomy program (I use a freebie copy of SkyMap) and set it for an observing location high in Canada at this time of the year, you may find that sunrise is around 2am and sunset around 10pm. Go up high enough, and in about a month the sun will neither rise or set, staying above the horizon for 24 hours.

Down near the equator (or UP for me), sunset always occurs close to 6pm and sunrise close to 6am.

BABB people: Is it possible that that paragraph in the article is poorly written, or otherwise wrong? Because the more I look at it, the less sense it makes even to me.

I've got NASA's tables of "when to see the eclipse" for Alaska-Canada, and I don't see any mention of "changing the clocks in Canada to May 30".

http://sunearth.gsfc.nasa.gov/eclips...003-Tab15.html

I also don't see any mention of "changing clocks because of the International Date Line" on the main page.
http://sunearth.gsfc.nasa.gov/eclips...3/ASE2003.html

So, huh? Now I don't get it, either...

It is not wrong, but it is, I think, poorly written.
The article doesn't say anything about "changing clocks" either. You're reading "set" as an action verb. It's not. "When it's 5:00pm GMT, my clock is set to 12:00noon." That doesn't mean my clock gets changed when it's 5:00pm GMT, it's just telling you what my clock is when it's 5:00pm GMT.

The article is just telling you what the clocks east of the IDL are at the time of the eclipse, not what they should be changed to at the time of the eclipse.

If the eclipse is happening at sunrise...it will be seen at sunrise for EVERYONE that can see it wherever they are in the world and regardless of the time on the clock´s.
We can all agree to that!!

But this article accually states that there is a place, in canada, where people will see the eclipse at sunset... a sunset is about 16 hours after sunrise (or 8 hours before).

Jigsaw: Hear! Hear! to your post about cutting people a little slack and giving them the benefit of the doubt. I'm pretty appalled at the arrogance and high-handed know-all behaviour of experienced BABBers who should know better.

For instance, I was never taught anything about astronomy when at school, and I've long wished that I had been. I used to ask "dumb" questions once too. Haven't we all done it? I had a hell of a job trying to understand retrograde motion until I saw a good illustration, and as a photographer I often wondered why so many photography books said that soft light could be found at a north-facing window. That was nonsense to me, because those are the windows the sun streamed through. Eventually I learnt why.

This impatience and arrogance seem to be, from what I see on the idiot-box, along with throwing tanties and abusing people, "The American Way." Thank God there's none of it around where I live.

No. If an eclipse occurs here at sunset it will occur at sunrise in Spain, or on the same longitude as Spain. (Unlike for most of you in North America, there is solid ground on the opposite side of the world to me.)

Right now it's 3:17am on Saturday 24 May. Only those who live a few degrees west of my longitude will be on the same time.

Ok guys let's cool off for a bit

Skywatcher: the questions you are asking are fine, you are curious and want to know about astronomy, but that belongs to the other forums in this board. So please make them there. I did answer your question on SWAN because I figured you wondered if it had to do with Planet X. But Kaptain K is right, this must be asked in the General Astronomy forum.

Guys: as far as I can understand, he is asking reasonable questions, if he knows nothing about Astronomy this is to be expected, so far he seems to want to learn, it might be considered annoying but doesn't make him a troll.
