i mean who is responsible for standard time, which apparently sucks.
The 1884 International Meridian Conference selected clock of the Royal Greenwich Observatory as the standard of measuring the hours of the day. The concept of time zones was still a ways off, and communities set their clocks by the sun's noon position, more or less. Probably on a given date.
Rail travel and instantaneous telegraph traffic brought out the problem of local time standards, as identifying a message time or scheduling a train proved incredibly difficult. In North America, the railroads simply decided on 5 time zones and enacted it. Local communities complied or didn't, as they saw the need. The standard time was enacted into law in 1918, when daylight savings time was introduced.
Standard time measures the day with noon the time of the sun's highest position. Daylight Savings was introduced to make the sun "later" against the clock for agricultural purposes, so farmers could coordinate their schedules with other business interests, and still have time to work the fields. In winter we revert to Standard time because the late light is no longer needed. Standard time also conforms to the world-wide adoption of Greenwich as the standard clock.
The width and occasional overlap of time zones introduces other issues. My home is only 20 miles or so west of the Eastern time zone, so I live very early in Central, meaning it gets light earlier and dark earlier for me than for my cousin in Texas, by almost a full hour.
The absolute worst part of changing the clock is that my animals don't understand. They come into my room expecting the day to start an hour earlier than they did last week, and they won't leave me alone!
When I was a junior in high school, we had to share our building with new school. All the enrollment had been set, everybody had been assigned this school or that, and the contractor fell behind. The building wasn't ready, but the administration was, and they couldn't put everything back the way it was in time, so we went to school from 6:30 AM to noon, and they went from 12:30PM to 6

M in our classrooms. With no lunch needing to be served, our cafeteria became their offices. This was the year Nixon extended Daylight Savings into the winter for the energy crisis, so the sun came up sometime during 3rd period!
