Are these taking into account countries that have daylight saving time? -- Francs2000 | Talk 22:30, 23 July 2005 (UTC)[reply]

Not sure. Any idea? I think the list at time zone is to long, so I thought about creating this zone articles. Tobias Conradi (Talk) 22:38, 23 July 2005 (UTC)[reply]

I'm certainly no expert myself but for example the UK has two timezones: one (GMT/UTC) for the winter months and the other (BST/UTC+1) for the summer months. I don't how many/if other countries do that. -- Francs2000 | Talk 22:40, 23 July 2005 (UTC)[reply]
maybe countries with daylight saving time have to be listed twice Tobias Conradi (Talk) 23:00, 23 July 2005 (UTC)[reply]

Amsterdam Time was twenty minutes ahead of UTC, not forty minutes; I changed the template appropriately. But should UTC+0:20 even be in this list, seeing how no one uses this time zone now? It seems more appropriate to a list of historical time zones; is there such a list on Wikipedia? Izzycat 19:19, 27 November 2005 (UTC)[reply]

If there is too much, maybe they can be seperated. For now I would leave historic ones. Tobias Conradi (Talk) 04:35, 23 March 2006 (UTC)[reply]

current time[edit]

User:Ed Poor made nice current time templates like 19 resulting in "00:40" can this current-time thing be integrated in the template:timezones? In most cases the page name should be sufficient. I would like to use page name to make it more robust against vandalism. A variable can be changed in hidden - page name is allways obvious. Tobias Conradi (Talk) 04:37, 23 March 2006 (UTC)[reply]

I moved the templates from lower case to upper case.

for the zones that have a Ed Poor template I found a way to include the data. For the others I don't know how to do it. The Ed Poor system uses Template:Utc via a parameter which is _not_ the UTC offset. Hopefully he can help soon. Tobias Conradi (Talk) 05:34, 23 March 2006 (UTC)[reply]

To avoid using negative numbers, I added 24 to UTC offsets like -5 (Eastern Standard Time) and got 19. So the current time in New York City is 00:40 until daylight saving, and 01:40 during daylight saving.
I'm not planning any more template work on this. It should be translated into Javascript or PHP. --Uncle Ed 16:28, 23 March 2006 (UTC)[reply]
I totally agree with Ed... this is better handled by someone making a feature request -- that is, if showing the current time is even really necessary. Can't people just do the math? -- Netoholic @ 15:58, 24 March 2006 (UTC)[reply]
The feature request you suggested has been made. Like it? --Uncle Ed 02:10, 24 April 2006 (UTC)[reply]

Daylight time[edit]

I've added daylight time to UTC-7 and UTC-6. Check out the link structure I've created there, and compare it to the Daylight time link at UTC-5. I think the way I did it is better because Central Daylight Time redirects to Central Standard Time Zone. What does everybody else think? EWS23 | (Leave me a message!) 00:38, 8 April 2006 (UTC)[reply]

Your way seems better to me. For daylight using areas we could maybe add data about when the area really is in the specific UTC-zone. Same for the DST-zones, add when they are applied.

BTW: Some countries have their own article in Category:Time by country, so maybe instead of linking to "<Countryname>" maybe better to "Time in <Countryname>". Tobias Conradi (Talk) 04:46, 8 April 2006 (UTC)[reply]

Time zones and time offsets[edit]

I think "Time zone" means a geographical region where just about everybody observes the same standard time.

I think a "Time offset" means a particular amount of time subtracted from or added to UTC to get the current local time - whether it's standard time or Daylight saving time.

In any particular time zone residents either observe standard time all year round (as in Hawaii or most of Arizona) OR they observe standard time in winter (around 3/7 of the year) and daylight time in summer (4/7 of the time). Note: we are dividing the entire year roughly into "winter" and "summer" here just to facilitate discussion. We all know that European Summer Time actually begins early in Spring, etc. --Uncle Ed 17:17, 20 April 2006 (UTC)[reply]

New Zealand historic time zones[edit]

New Zealand established New Zealand Mean Time (NZMT) in 1868 as GMT+11:30, with the Chatham Islands 45 minutes ahead on GMT+12:15. New Zealand's Summer Time Act 1927 moved the clocks forward to GMT+12:30 (mainland) and GMT+13:15 (Chatham Islands), but this wasn't popular so was changed after one summer with the Summer Time Act 1928, changimg it to a 30 minute advance in summer ... essentially the same as the current NZST and CHAST but only in summer time observance period. In 1941 (under war time emergency regulations) this half hour advance from New Zealand Summer Time (NZST) became New Zealand Standard Time (NZST)[citation needed], with the Chatham Islands still 45 minutes ahead. No further adjustment was made for additional summer time, as the regulations treated the whole year as on special summer time, renewable annually. The Standard Time Act 1945 abolished the unused standard of NZMT so that from 1946 NZST (NZStandardT, rather than NZSummerT) became the defacto 'standard'. The 1945 act didn't differentiate for the Chatham Islands so the islanders just ignored NZST and carried on using their long-established time zone of NZST+00:45, and in 1956 the 1945 act was amended to reflect this, with the change officially coming into force on 1 January 1957. The Time Act 1974 re-established daylight saving time of one hour, firstly from November 1974 to February 1975, and then every summer since with several tweaks to starting and ending dates. As you can see above there's [currently] three redlinks for the three missing time zones. (talk) 08:52, 14 December 2018 (UTC)[reply]
