"The clock on the Kremlin's Spassky Tower is a regular weight-driven mechanical clock devoid of any electronic gadgetry; for that reason, its hands are always adjusted manually," Devyatov pointed out.
According to him, the annual transition to summer and winter time does not affect the clock's accuracy or performance.
"The Spassky Tower clock is in a good working condition supported through regular technical maintenance," Devyatov said.
Hands of the two-face clock on the Grand Kremlin Palace are also to be put forward. "In addition to that clock, the Grand Kremlin Palace holds a unique collection of antique clocks and watches," the FSO spokesman pointed out.
"All the clocks in the Kremlin's working quarters will be similarly set forward to summer time," Devyatov said.
Russia goes to "summer time" from March 27 to October 30 this year. All the clocks in the country are to be put forward one hour in the small hours of Sunday.
Russia first practiced transition to "summer time" in 1917.
In 1991, the country experimentally withheld the practice, but due to overloads in the national energy system Russia swiftly re-introduced annual transition to "summer time" in 1992.
