[tz] Uzbekistan - insufficient location desciption

[Tobias Conradi]

tzdata2012c/asia
no location comment except
# Uzbekistan
for
Asia/Samarkand
Asia/Tashkent

Also no other comment, telling where the Uzbekistan info comes from.

tzdata2012c/zone.tab
Asia/Samarkand	west Uzbekistan
Asia/Tashkent	east Uzbekistan

No definition for "West Uzbekistan" or "East Uzbekistan" found.

Trying to improve:
Asia/Samarkand per definition includes
Samarkand Province, where Samarkand is located.

"west Uzbekistan" if only contrasted by "east Uzbekistan" and using the map at
http://en.wikipedia.org/wiki/Provinces_of_Uzbekistan
likely additionally refers to
Karakalpakstan, Xorazm, Buxoro, Navoiy

Uncertain remain
Jizzax (north east), Qashqadaryo (south) and Surxondaryo (south).
But since the two southern country subdivisions, if looked at as one
unit, border Samarkand, they may be included in Asia/Samarkand.

This leaves five provinces, with Jizzax six, for the Asia/Tashkent.

If that is the case zone.tab could be improve by
Asia/Tashkent	east Uzbekistan (Andijon, Fergana, Namangan, Tashkent,
Sirdaryo [, Jizzax])
