Adding your country to the table

Hey mappers, when adding your country to the table, please don't forget to change the rowspan="x" value for the WUT +-y cell to x+1, e.g. rowspan="8" | WUT +1 should become rowspan="9" | WUT +1 after you add your country. Not doing it causes inconsistencies within the table. Thanks --Eklas (talk) 14:40, 9 February 2018 (CET)

Time-zones general

I created this map with the proposed World Time Zones for the existing continents and countries.

Very impressive work, and useful too. Thank you. I would like to request (suggest?) one of those "antisocial" +30 time zones (cf. India, South Australia, Iran... on Earth) for my my country Mahhal. Thus make it +4:30 for the whole country, since it straddles the +4/+5 line. It suits their history of having been a "closed" country until recent decades.--Ardisphere (talk) 06:46, 23 August 2014 (CEST)

Great map. The only odd thing is that the time zones on the left are wider and those on the right are narrower. If there are 24 hours in a day then ideally each time zone should have the same basic width of 15° (360° ÷ 24 hours = 15°).
So... something like this, maybe:
This may also be the place to think about why the Prime Meridian is located where it is. Perhaps it was the location of the westernmost land or island known to the Ulethans at the time? Perhaps it was the location of some holy site in a holy land? (Of course if the Prime Meridian was based on a large city then it might serve as the center of the first time zone, in which case all these zones would be shifted 7.5 degrees...) --Isleño (talk) 08:48, 23 August 2014 (CEST)
Yes, latitude 0° was formerly at the eastcoast of Tarephia and so are (in Latina) places named as "Tentoten" (10° S, 10° W) or "Longitude Dos" (2° W) and near Van Pelt an observatory exact at O°. All this had changed over 50 ° latitude. So please not more a changing of the O°. Let us see it so: Former there are some different definitions of the 0° - an then an international conference has hammered fast this line west of all points of Uletha or Tarephia. And so the time zones are logical - one hour = 15°. --Histor (talk) 09:59, 23 August 2014 (CEST)
Is it not better, to set the boundaries of time-zones to -7,5° / 7,5° / 22,5° etc, so that the middle of a time-zone is 0°, 15°, 30 ° etc? --Histor (talk) 02:13, 2 September 2014 (CEST)
It depends on what the Prime Meridian represents. As I mentioned above, if the Prime Meridian was chosen to run through a great city (as it was on Earth) then yes, it would probably be the center of the first time zone. But if it were based on a remote "westernmost point" of some kind, then it could mark the beginning of the first time zone, which would therefore be centered on 7.5° instead of 0°. The reason FBG and I didn't draw the time zone boundaries along 7.5°, 22.5°, etc. is because the underlying map has lines at 0°, 10°, 20°, 30°, etc. Looking at those lines, it is much easier to draw 0°, 15°, 30°, 45° than 7.5°, 22.5°, 37.5°, 52.5°. We should probably determine the story of the Prime Meridian before deciding whether it marks the center of the first time zone or the beginning of it. --Isleño (talk) 09:10, 2 September 2014 (CEST)

Indeed - but it was only the information, in which manner later can be a convention. Til this I set on 45° for Latina. If the time-zone later is 37,5° or 52,5 °, I can change. --Histor (talk) 09:54, 2 September 2014 (CEST)

Which map is official OGF timezone map? Pasundan-Padjadjaran is at diferent time zone in those map, CPP is at +7 in the first map ,while in the second map at +8, so which map i shoud take as a reference for my country timezone ?... Okiazr (talk) 21 March 2015

Unfortunately neither is official. If the first time zone begins at 0° (i.e. centered on 7.5°E) then Pasundan-Padjadjaran would be +8, as in the second map. If the first time zone is centered on 0°, however, then Pasundan-Padjadjaran would actually be +9. You can probably just choose whichever number you like better, 8 or 9.
The 2nd one looks very nice and is more... detailed? I'd rather use this timezone map :) Zniwek (talk) 21 March 2015

I would like to present a new design for the Time Zones, since I noticed some errors in the previous maps, the main error: The "Central Time Zone" (± 00:00) goes from the meridian -7.5 ºW to 7.5 ºE, not from 0 ° to 15 °E, this causes all other meridians to be incorrect at +7.5 °.UsuárioPar (talk) 00:38, 14 June 2018 (CEST)

Time zones are not given by nature, but by convention (like the longitude generally). In Europe a time zone is set bei 0°, 15°, 30° and so on. The Middle European Time Zone (MEZ) is the time of 15° East - and so - theoretical - the time from 7.5° to 22.5° East. --Histor (talk) 01:28, 14 June 2018 (CEST)

The map on the main page does show all time zones as 15º in width. Unlike the real world, we've decided (for various reasons discussed above and accepted by common practice) that time zones are not centered on multiples of 15 but begin and end at those points. I think it's perfectly fine to have 0º–15ºE be a time zone (essentially centered on 7.5ºE). It's been agreed upon by practice for a while, and I think it works great. — Alessa (talk) 17:10, 14 June 2018 (CEST)

Loading map...

I just created a multimap of the suggested timezone boundaries, and while doing so I realized that having timezones centered on 7.5's will make for a +11 on one side and a -12 on the other, or +12 and -11. For this map, I made WT+0 on the eastern side of the prime meridian; if we decide it to be on the western, we could change that.

time zones in practice

(Note: There is now an option to set "Timezone" in the Infobox country template)

  • Latina has set his time zone to the latitude of 45° East, because 30° or 60° is outside of the land and not practicable. So the time of Latina differs 3 h from the 0°-time. [in formerly times Latina had the time of 0°, but since the changings about 50° it is no good value]. --Histor (talk) 02:06, 2 September 2014 (CEST)
  • Zylanda set his time at 120° E (8 hours difference from 0°). This is very satisfited, because the capital Elegantia lays exactly at this latitude. --Histor (talk) 02:10, 2 September 2014 (CEST)
  • Balonis has set its time zone to +8:00. I wanted to notice this because on the map above you can't see Balonis yet (the map is very outdated :p) Niels20020 (talk) 17:21, 30 August 2016 (CEST)
