DomnoniaAug 2 2005, 09:10 PMYuunliAug 2 2005, 06:15 PM The Republic of Yuunli has decided to adopt a standard time for the whole nation. Yuunli Time (YT) shall be exactly one hour behind IDU Standard Time.
The sun is at its highest point at the following times:
- Miervatian Line: 11:00 YT
- easternmost point of Mich-Inzl: 11:10 YT

Ok, just to get this straight.
If it is 12:00 in Miervatia according to IDU Standard, what time would it be in all of Yuunli.
I'm guessing 11:00?[/quote]
Yes, that's it.
Two things I realized only recently:
1) So it's 700 km rather than 7 degrees of longitude? In fact that makes more sense. As a matter of fact, I live at exactly 7? east IRL, and the local time is a little bit closer to WET than to CET. That's why the sun is at its highest point at about 11:35 GMT = 12:35 CET = 13:35 CEST (Central European Summer Time).
On Earth, you have a difference of 1 hour every 15 degrees of latitude, or of half an hour every 7.5?.
Compared to Earth, the IDU planet would have an equatorial circumference of 33,600 km if 700 km meant a time difference of 30 minutes. That corresponds to a diameter of approximately 10,700 km or 84% the size of Earth, where you have a difference of an hour every 1670 km at the equator.
2) What about metric time? Do we really have to use the unintuitive and old-fashioned habit of calculating with 60 seconds per minute, 60 minutes per hour, and 24 hours per day? Why not let a day have 100,000 instead of 86,400 seconds? Then one new second would correspond to 0.864 traditional seconds. Then a kilosecond will be 864 seconds = 14 minutes 24 seconds.
Or, if we assume the same rotational velocity as Earth - 465.11 m/s - for our planet, a day would have 20 hours 7 minutes 20 seconds. That's 72,440 traditional seconds. So if we define an IDU planet day to have 100,000 new seconds, one new second will correspond to 0.7244 traditional seconds. Then a kilosecond will be 724.4 seconds = 12 minutes 4.4 seconds.
EDIT
Alternatively, you can define a new minute to be 1/1000 of a day. That would make 1 NM = 1 minute 26.4 seconds / 1 minute 12.44 seconds, 10 NM = 14 minutes 24 / 12 minutes 4, 100 NM = 2 hours 24 minutes / 2 hours 44 seconds, 0.1 NM = 8.64 s / 7.244 s, 0.01 NM = 0.86 / 0.72 s ;-)
