Note that the Yukon had two time zones until 1973, but the
database already knows that.  America/Whitehorse is the
other side of the split.

If you are keeping all that might be better not to lose the
reference to the federal statute

   Interpretation Act, R.S.C. 1985, c. I-21, s. 35(1)

since that is an interesting bit.  While the territorial
government explicitly redefined Yukon Standard Time to be
(entirely) UTC-8 in 1973 the federal government laws apparently
believe that Yukon Standard Time (and the standard time in the
Yukon too, from the wording) is still UTC-9 so keeping that
reference maybe answers the issue of the database no longer
abbreviating Yukon Standard Time (by the Yukon government's
definition) to YST.  The way the database does it now,
representing it as a change to PST, seems to me to be more
useful anyway.
