[tz] [IANA #1173666] Time zone change - Yukon Canada

[Chris Walton]

To me it does not make sense to call it Yukon Standard Time when the UTC offset is exactly the same as Mountain Standard time (UTC -7).

I uploaded some new maps to Wikimedia Commons.  I hope they help to visualize the situation.  I did not apply a YST label to the maps.
