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.
