October will become the longest month of the year when several countries across the globe will adjust their clocks one hour backward a week from now.Experts from the State Metrology Center in Russia say that near the start of spring, clocks are adjusted forward one hour and in autumn, adjusted one hour backward which is mainly done on the last Sunday of March and on the last Sunday of October. Time zones are adjusted seasonally into standard and daylight saving or summer variants. Daylight saving time zones or summer time zones include an offset typically plus one hour for daylight saving time. The daylight saving time idea was put forward by US statesman Benjamin Franklin.Nowadays, 110 out of 192 countries adjust their clocks twice a year.
