| # From Rives McDow (1999-11-08): | ||
| # On October 31, when the rest of Nunavut went to Central time, | ||
| # Pangnirtung wobbled. Here is the result of their wobble: | ||
| # | ||
| # The following businesses and organizations in Pangnirtung use Central Time: | ||
| # | ||
| # First Air, Power Corp, Nunavut Construction, Health Center, RCMP, | ||
| # Eastern Arctic National Parks, A & D Specialist | ||
| # | ||
| # The following businesses and organizations in Pangnirtung use Eastern Time: | ||
| # | ||
| # Hamlet office, All other businesses, Both schools, Airport operator | ||
| # | ||
| # This has made for an interesting situation there, which warranted the news. | ||
| # No one there that I spoke with seems concerned, or has plans to | ||
| # change the local methods of keeping time, as it evidently does not | ||
| # really interfere with any activities or make things difficult locally. | ||
| # They plan to celebrate New Year's turn-over twice, one hour apart, | ||
| # so it appears that the situation will last at least that long. | ||
| # The Nunavut Intergovernmental Affairs hopes that they will "come to | ||
| # their senses", but the locals evidently don't see any problem with | ||
| # the current state of affairs. | ||
|
|
||
| # From Michaela Rodrigue, writing in the | ||
| # Nunatsiaq News (1999-11-19): | ||
| # http://www.nunatsiaqonline.ca/archives/nunavut991130/nvt91119_17.html | ||
| # Clyde River, Pangnirtung and Sanikiluaq now operate with two time zones, | ||
| # central - or Nunavut time - for government offices, and eastern time | ||
| # for municipal offices and schools.... Igloolik [was similar but then] | ||
| # made the switch to central time on Saturday, Nov. 6. | ||
|
|
||
| # From Chris Walton (2022-11-06): | ||
| # The implication is that Pangnirtung and Qikiqtarjuaq have observed Eastern | ||
| # Time as far back as 1984 (and likely even further back than that). | ||
| # It is possible that these communities never actually observed Atlantic | ||
| # Time, but that would be difficult to prove. | ||
| # From Paul Eggert (2022-11-06): | ||
| # This is in 'backzone' as we have no good evidence that Pangnirtung differs | ||
| # from America/Iqaluit since 1970. A Google Books snippet view of | ||
| # volume 2, page 186 of "Pilot of Arctic Canada", published 1959 by | ||
| # the Canadian Hydrographic Service, suggests (though does not state) | ||
