During his state-of-the-nation address to Russia's parliament he also suggested discussing the use of daylight saving time and standard time.
"All the advantages of economizing and evident inconveniences in changing time are necessary to assess. I hope experts will give us objective answers to these questions," the Russian president said.
Russia was divided into 11 time zones in 1919. The Soviet Union adopted the system in 1924.
The country changes to daylight saving time starting from the last Sunday in March until the last Sunday in October.
Last July, the industrial policy committee at the Federation Council, the upper house of Russia's parliament, proposed abolishing daylight saving time over adverse health effects.
