Like many New Zealanders, I'm not a fan of time. To be more precise, I'm sick of it being 9am here and 5pm yesterday somewhere else. It's confusing.
It would be easier if everyone ran at the same hour. If no matter the solar time in a given location, we all had the same clock number. Some lunchtimes would occur at 3:00, others at 11:00, and some at 12:00, but what does that matter? The sun's position would be the same - just the clock number assigned would be different. Your pie, jam doughnut and V will taste the same no matter the clock number. Under this system, booking international online meetings would be easier. You could tell five people in different parts of the world, '11:00, September 19', and they'd all know when that was. The middle of the night for some, mid-arvo for others, but the number would be the same.
Time zones are a simple concept in and of themselves. There are 360 degrees of global longitude. Dividing that by the number of hours in a day creates 24 15-degree zones, 1665km wide. A timezone is offset by the number of zones it is from the Prime Meridian, an imaginary line that was placed through the globe from Greenwich in 1884. UTC (Coordinated Universal Time) is clock time rather than solar time. My question is, why do we bother offsetting? It's just a number.
Time was originally measured by the placement of the sun overhead. A sundial dictated what time it was in each small region. This became problematic with the advent of trains. They were fast enough to make different times in different places an issue. Not knowing when another train will be on a track tends to cause horrific head-on collisions. So, a standard measure of time was set, and eventually extended around the globe. A great system in Victorian times, which has become slightly annoying since the advent of international calls, and now free Zooming.
