Units of Time

Hours/Minutes; Systems That Use Earth Time

Removed by Ysselt: Some old systems (such as repair shops) use Earth time, but this is out of character.

Some systems clearly use OOC time. (The mere fact that it says "hour" or "minute" does not make it OOC, but you can tell whether it's meant to be OOC or IC by the length of time.)

I think that this comment should stand, but I moved it to another section, since it never really belonged in the anlas section.

I don't think you can say an hour is ooc but a minute isn't. We were told those uses weren't OOC - we have to call it something else, in my opinion, not OOC. RL Time pershaps, but not OOC. Also in every instance of the use "minute" or "hour" in game, it's RL time duration. Why isn't it so difficult to say the definition of a IG minute and an IG roisaen aren't the same, but different measurements of length of time but both are equally accepted as being IC. Just don't think you can have it both ways saying minute isn't OOC and then later calling hour OOC when we just had a post saying it wasn't. --Ysselt 10:57, 6 May 2010 (UTC)
As I said before, the mere use of the term "hour" doesn't make it OOC. "Hour" can be IC or OOC depending on how it is used. There is an Elanthian unit called the hour, which is defined as 15 minutes, and some people also refer to anlaen as "hours" (though this usage is ambiguous.) "Hour" is OOC when it is used to mean 60 minutes.

However, the issue of the term "hour" is separate from the fact that Earth time is still used in some systems. (That's why I moved it to a more general section and omitted any reference to "hours.") Most of these are old systems that may have been released before the time system. In other cases, Earth time was chosen for the convenience of the player. --Isharon 17:58, 6 May 2010 (UTC)

I personally disagree with the assessment of terms like 'minute' and 'hour' being strictly out of character. They are simply Common/informal terms for concepts more "properly" or formally expressed in Gamgweth. I don't want to edit the article to reflect this without trying to provoke a little discussion first, though. Reene 04:44, 6 December 2007 (CST)

I agree that minutes and hours can't strictly be considered OOC or else every new player would be forced to be OOC simply because of ignorance. --Kraelyst 06:40, 6 December 2007 (CST)

Andu vs. Day

Rangergls's Revision to the Elanthia -> Earth Conversion Chart: Despite the literal meaning of "andu," an andu is not one day long. The Elanthian andu or week spans four Elanthian days (or one Earth day). See The Elanthian Calendar. --Isharon 21:26, 7 May 2010 (UTC)

Each of the months is, as was pointed out above, divided into 10 "weeks" of 4 days each. These groups of 4 days are each named after one of the great divinities of Elanthia. . . . The word "andu" (pl. andaen) literally means "day" in High Gamgweth but since each of the "days" here is actually four days long, "weeks" is the more common translation.

Time Begins

Simple, but it's something. Just took the in game help text and wikified it. There's room to expand the article; needs names of years, and names of months. Farman 15:34, 24 March 2007 (CDT)

According to my original calculations, the DR Epoch (0 years and 0 days since the Victory of Lanival the Redeemer) occurred on 1901-05-26 19:45:00 UTC, or 2,164,853,700 seconds before the UNIX Epoch (1970-01-01 00:00:00 UTC) --Dandin 02:49, 13 September 2010 (UTC)

Sun Rise/Set Formula

The following is a copy from a post on the boards(I forget by who) on how to calculate the rise/set time of the sun based on the day in game. I'm adding it here for safe keeping, just in case someone wants to wikify the information.

In an effort to replicate the time portion of the time/weather window in e-scape on Avalon, Delvan had gathered a great deal of data concerning the rinsing and setting of the Sun and moons. I took a look at his sun data and ended up with this. X-post from Avalon/YASSE forums

Got it! Rise/set times follow a sine function. An event (rise/set) will occur every 3 hours modified by the sine function. The difference between the rise modifier and the set modifier is a phase shift of pi. The correlation to the IG date is day*(pi/400). The frequency of the changes is 2, the amplitude is the (maximum time shift - minimum time shift)/2, the vertical shift is the average time shift.

Sunset formula.png

f(day) = 0:30 * sin(2(day*pi/400)+X*pi/2) + 1:15 X = 1 for rise time X= 3 for set time

The R^2 value (a measure of how well the formula predicts actual data) is 4 seconds when compared on Delvan's data points. A plot of the residuals is statistically random. So there you have it, you too can calculate when the next sun event will occur, just by having the IG date. Don't forget to convert the sine function to minutes before multiplying and adding. Data points were gathered under PST.

Elanthia can't be flat

From a room description on the Southern Trade Route, between the Crossing and Leth (one room south of the skunk):

Along the north, the trees and shrubs are fairly homogeneous, much the same as other wild growth at the same latitude and altitude anywhere in this hemisphere of Elanthia.

By definition, you can't have a hemisphere without a spherical planet. --Aracin 09:44, 24 February 2009 (UTC)

Time Calculator

The time calculator linked here is currently down and has been for a few days. I'm currently writing a Genie script to do the conversions for me, but if I change it to a PHP script as well would Elanthipedia be willing to host the page? --Maje 01:43, 15 July 2009 (UTC)

Is there any interest in the enhancement of the before mentioned time calculator to include solar and lunar events (sunrises, sunsets, and lunar cycles)? --Dandin 02:40, 13 September 2010 (UTC)
