Time zone

For information, time zone is a region of the earth that has adopted a uniform standard time, usually called as the local time. Most adjacent time zones are exactly one hour apart. Standard time zones can be found by dividing the earth's spheroid into 24 lunes. The local time in neighboring zones would differerent by one hour. However, political and geographical practicalities can result in irregularly-shaped zones that follow political boundaries. Before used time zones, people used local solar time. The use of local time became increasingly. The increase in worldwide communication has further increased the need for time references to one another.
