Why time zones are not straight?

Why are time zones crooked?
Why Are the Time Zones So Crooked? Time zones are crooked because it is up to each government to regulate them in their country. There are standard time zones for the world, but where exactly those lie and whether to split the country up according to these is a decision made by individual nations.
Why do time zone boundaries not always line up perfectly with lines of longitude?
Why do time zone boundaries not always line up perfectly with lines of longitude? To avoid any confusion time zones go around towns, cities, and areas of a country. Contour lines never cross because an area of land cannot be at more than one different elevation.
Why are the time zone cut off lines not straight or exactly 15 degrees apart?
STANDARD TIME ZONES The earth undergoes one complete rotation along its axis in 24 hours. For a complete rotation on its axis, the earth passes through 360 degrees. For every one-hour time, a point on the earth moves through 15 degrees of longitude (360/24 hours).

Why do states have different time zones?
Every city in the United States used a different time standard so there were more than 300 local sun times to choose from. Time zones were therefore a compromise, relaxing the complex geographic dependence while still allowing local time to be approximate with mean solar time.
Why do we have time zones why doesn’t every country have 6am at the same time?
Every 24 hours, the Earth makes a complete rotation. We call each full turn a day. Noon would be the middle of the day in some places, but it would be morning, evening, and the middle of the night in others. Since different parts of Earth enter and exit daylight at different times, we need different time zones.

Why are some time zone lines not straight?
Time zone lines are not always straight in order to accommodate the desires of nations within the boundaries of the zone. The irregularity is mainly due to political factors and has nothing to do with geography or any other natural cause. Time zone lines, when not deflected for political reasons, are 15 degrees of latitude in width.
How are the boundaries of the time zone arranged?
The boundaries are arranged over both land and sea. Each line is one hour earlier than the last line to the east, but within the boundaries of the time zone itself, time is not set earlier in the west than in the east.
