The subject of today's Geo Quiz, telling what time it is in Russia, can be a tricky business. That's because Russia has 11 times zones.

Alexander Krivenyshev runs worldtimezone.com to help travellers keep track of time around the world. He knows Russia like the wristwatch on the back of his hand...so here's his list:

Krivenyshev: "Let's start from east to west, especially as I was born in Siberia I would rather to start from the Far East Siberia part of Russia. So the first time zone starting from the east it will be the Kamchatka time zone, next on is Magadan, after that Vladivostok and Sakhalin Island, after that the place where I was born Yakutsk, the coldest place in the northern hemisphere, after that we go to the Lake Baikal region, it's Irkutsk region, then Krasnoyarsk region, then Novisibirsk/Omsk region, after that it will the Urals Mountains or Yekaterinberg region, and after that we are one hour in front of Moscow , its Samara region, then after that it will be most polulated Moscow region with St. Petersburg, Grozny, and Murmansk..and the last region it will be Kaliningrad region."

Got it? From Kamchatka in the east to Kaliningrad in the west...Russia spans 11 time zones.

Kaliningrad Time UTC+2
Moscow Time UTC+3
Samara Time UTC+4
Yekaterinburg Time UTC+5
Omsk Time UTC+6
Krasnoyarsk Time UTC+7
Irkutsk Time UTC+8
Yakutsk Time UTC+9
Vladivostok Time UTC+10
Magadan Time UTC+11
Kamchatka Time UTC+12

Alexander Krivenyshev has crossed them all many times on the trans-Siberian railway. He admits the multiple time zones can be confusing, even when it comes to calculating what time is tea time?

Krivenyshev: "Actually yes you can take a train from Moscow to Vladivostok , it will take about 5-6 days, so yes you can have about 5 tea times, 5 times or 7 times!"

Krivenyshev's favorite stop along that long journey across Russia? He says its just past Lake Baikal, the most beautiful part of Siberia.
