Yesterday’s CBC News report “Nunavimmiut have wound back their clocks
for the last time”[1] is so light on details that for now I am merely
attaching a draft patch to this email for review, rather than installing
the patch into the development repository.
I found no announcement of the change at www.makivvik.ca. Although I
asked for more details by using the form at
<https://www.makivvik.ca/contact/>, these sorts of contact forms often
do not work, so if anyone has access to more-authoritative info than the
CBC report, please let us know. Among other things, details in the news
report make me wonder how likely Makivvik would reconsider its decision
before the change would take effect about a year from now.
