Notes from the Maintainers

Source: backzone (Lines 754 to 798)

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)
that Pangnirtung observed EST then.
