Fix spelling of Kyiv timezone

You should provide some reference to international database of city names, or anyone will change city names as he wish.

Did some quick Google research, found this article, "Kiev or Kyiv?": http://www.infoukes.com/faq/kyiv-2/

"The major academics, however, such as the world's leading Ukrainian linguist, Prof. George Shevelov (Columbia University, emeritus) of New York and Dr. Edward Burstynsky, Professor of Linguistics at the University of Toronto, approve of Kiev as the correct form in English for the capital of Ukraine.

....Ukrainians in Ukraine have no feeling for the English language and they cannot be expected to appreciate the implications of using Kyiv, or the ugly Kyyiv, in place of the correct and familiar English form Kiev."

I can't vouch for the accuracy of this article, but it does seem to indicate that there's no consensus as to whether Kyiv is preferable to Kyev.

It's ok if the spelling is changed to Kiev. But "Kyev" (with "y" instead of "i" as in "Kiev") is certainly wrong.

Ok here's some compelling pro-"Kyiv " evidence:

1. US State department refers to it as Kyiv: http://www.state.gov/r/pa/ei/bgn...

2. Ukrainian constitution states "The capital of Ukraine is the City of Kyiv": http://www.rada.gov.ua/const/con...

3. Kyiv airport has letters KYIV on top: http://capitalofukraine.com/imag...
