replies: text: 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)

message: 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)
thread_title: Daylight time

message: 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)
thread_title: Time zones and time offsets

message: 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), 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. 119.224.77.162 (talk) 08:52, 14 December 2018 (UTC)
