So when some one says they go to work from 9am to 5pm people dont think that its dark if communicating to some one father away. Basically making the sun always rise at an 06:00 say and then setting around 19:00. Better question is who set the standard for GMT.

The circumference of a circle (including the Earth) is 360°. There are 24 time zones, one for each hour of the day, so each time zone is 15°wide. As Looking4Answers has already said the reason for time zones is so that wherever you are in the world daylight takes up the same hours. For navigation ships and aircraft use GMT, also called Universal Time (UT) regardless of which time zone they are in because navigation manuals are based on GMT.

"A time zone is a region of the Earth that has adopted the same standard time, usually referred to as the local time. Most adjacent time zones are exactly one hour apart" "Before the adoption of time zones, people used local solar time (originally apparent solar time, as with a sundial; and, later, mean solar time)." "clocks differed between places by an amount corresponding to the difference in their geographical longitude, which was usually not a convenient number." "This became increasingly awkward as railways and telecommunications improved" "This problem could be solved by synchronizing the clocks in all localities, but then in many places the local time would differ markedly from the solar time to which people are accustomed. Time zones are thus a compromise, relaxing the complex geographic dependence while still allowing local time to approximate the mean solar time."
