Thanks, I'll change it to:

CA	+690650-1050310	America/Cambridge_Bay	Mountain Time - west Nunavut

as per the followup discussion.

Thanks, I'll propagate these fixes too.

If the BBC says the centre of London is the modern Charing Cross, that's
good enough for me.  I assume the following will do?

GB	+513030-0000731	Europe/London

The following line in "Europe" shouldn't change, though:

Zone	Europe/London	-0:01:15 -	LMT	1847 Dec  1 0:00s

since that "-0:01:15" applies to the obelisk in question.

The tz database prefers the most common English spelling for the place
names in question; this is why we use "Moscow" rather than "Moskva",
for example.  "Kiev" is more popular than "Kyiv" in English.  The
other two names are similar.  If the English spellings change (which
is what happened with Mongolian and Kazakh names) we can revisit this.
In the meantime, I can add some comments about this, and change the
zone.tab entry to look like the following (a similar solution is
already in place for Greenland locations):

UA	+4750+03510	Europe/Zaporozhye	Zaporozh'ye, E Lugansk / Zaporizhia, E Luhansk
