Talk:List of time zones

From Wikipedia, the free encyclopedia

Does anyone know how the :30 and :45 time zones affect the presence of a certain hour?

For instance, if it is noon GMT, will it be noon in Alaska nine hours later (9:00GMT) and then noon in French Polynesia a half-hour after that (9:30GMT)?

If so, it seems that a particular moment on a particular day will actually happen 39 times. Is this actually the case?

Thanks. —Preceding unsigned comment added by 69.132.36.24 (talk) 16:11, 4 April 2006 (UTC)

[edit] Featured list?

This is a pretty nice list. If we add some references, we should nominate it as a featured list. Chanheigeorge 23:20, 3 May 2006 (UTC)

When this list was split off from time zone, the principal written references were left behind, the CIA and NAO maps. Even so, they are usually badly outdated, taking as much as ten years to reflect changes made by any government. Thus, individuals in the affected countries are much more important than any written source. This is contrary to the references cited by most articles which must be published. — Joe Kress 05:30, 15 May 2006 (UTC)

This source looks pretty detailed: Time Genie. Chanheigeorge 22:57, 4 May 2006 (UTC)

At first glance, Time Genie appears to get its information from Wikipedia, which it cites for more information. It even lists its 'countries' with Wikipedia idiosyncracies, such as alternative names. Furthermore, Time Genie does not give any time zone info—it only gives the current time in the selected country, from which the reader has to mentally derive the time zone. — Joe Kress 05:30, 15 May 2006 (UTC)

how do you come to the conclusion that tg may get the info from wp? Tobias Conradi (Talk) 01:24, 23 May 2006 (UTC)

[edit] Arctic and Antarctica

Does anyone know what time is used in Arctic and Antarctica? Dali 19:09, 19 June 2007 (UTC)

Each country in the Arctic determines its own time. Antarctic stations generally keep the time of their supply bases. For example, the Amundsen-Scott South Pole Station keeps New Zealand time, including its daylight saving time of UTC+13 in the southern summer, even though all ideal time zones converge at the South Pole. — Joe Kress 04:28, 21 June 2007 (UTC)

[edit] GMT to PST

So if someone told me to call them at 9 PM in England, does that mean 1 PM in California or 2 PM? Thank you. 71.243.206.213

California has UTC-8 and UK has UTC (both with daylight saving time), so the time difference is 8 hours most of the year. 9 PM in England is 1 PM in California. This is not valid around the time of start and stop of daylight saving time. Then it is hard to calculate it, see Daylight saving time around the world. -- BIL 07:23, 5 August 2007 (UTC)

[edit] Venezuela to change timezone to UTC -4:30

Starting Monday the 3rd week of September (2007) Venezuela will change its timezone from UTC -4 to UTC -4:30. RNV(spanish), ABN(spanish), Reuters. Artemis3 04:28, 18 September 2007 (UTC)

Small update: This will come into effect on September 24, 2007; not September 17. Oarval.org, eltiempo(spanish).

Historical fact: Venezuela used to have this time zone until 1964. Artemis3 04:28, 18 September 2007 (UTC)

This got delayed again, better wait for the official decree i guess. Artemis3 15:35, 24 September 2007 (UTC)

[edit] Principal cities

Great idea, but does every single time zone need four representative cities listed? One for Nepal, Afghanistan, etc. should suffice. —Preceding unsigned comment added by 98.199.120.129 (talk) 15:55, 16 October 2007 (UTC)

[edit] Changes of Zone - Time & Date

There are various mentions of places which have recently changed Time Zone - I've spotted Chihuahua, Venezuela, Georgia, Sri Lanka, Nepal, Kyrgyzstan, Taiwan, Peninsular Malaysia, Singapore, Marshall Islands, Phoenix Islands, Line Islands. I suggest that it would be well to have a separate list on this page for those and any other reasonably recent (or future) changes; the details in the main list could be replaced by links to that.

There are a few cases where territories have changed from one side of the Date Line to the other, thereby losing or gaining a day. That's of particular interest, and deserves its own list of all known changes however long ago. Alaska 1867, Marshall Islands, Phoenix Islands, Line Islands, at least.

Having separate lists will make omissions more obvious and more likely to be corrected.

[edit] Not in the United Kingdom

Guernsey, Jersey, and the Isle of Man are not parts of the UK.

[edit] Time zone change in the Phillipines?

I was just listening to Y101FM from the Phillipines and they were celebrating the New Year at UTC + 15:45 instead of UTC + 16:00 as one would expect seeing the list. Have I missed something? Dinsdagskind (talk) 16:00, 31 December 2007 (UTC)

[edit] Morocco and DST

BTW, I'm visiting Morocco right now and I'm told Morocco does observe DST from June 1 to September 27th. I found a brief article on the topic, but so far no other information (my search brought me also to this article). The article is not very good, and I'm trying to find some more independent confirmation, but I'm told by some Moroccans that this observance of DST is about five years old. 41.248.252.130 (talk) 21:24, 11 May 2008 (UTC)
