Perhaps the solution for America/Whitehorse and America/Dawson is to resurrect YST (-07). Would that be an option?
Yes, that would be a very nice idea. Yukon Standard Time (YST) is officially UTC-9 as defined in section 35 of the Canada's federal Interpretation Act. https://laws-lois.justice.gc.ca/eng/acts/i-21/page-4.html#h-279462 YST cannot be arbitrarily redefined to UTC-7 by anybody on this mailing list; nor can it be redefined by the Yukon government. Furthermore, I think that redefining YST is a bad idea because it would create ambiguity when dealing with old and new time stamps. YST(UTC-9) has been used as recently as 1983 in Alaska and 1973 in Yukon. -chris
Interesting, but then it seems that the quoted act has been flagrantly violated for 47 years as the Yukon observed PST instead of YST (despite the act being updated in 2015)! Furthermore, you would run afoul of that same piece of legislation in assigning MST to the Yukon :) It seems that it would require an amendment of this act to resolve the issue either way, since no proposed solution conforms to the definitions. Cheers, Erik p.s. Perhaps this legislation is why Linux installers, until recently, listed the long-unused Yukon Time as an option - I always wondered why...
