Time as we know it started on October 22, 1884.Hours were invented much later and seconds hundreds of years later. The first mechanical clock was built during the Renaissance.

How We Decide What Time It Really Is

Even after the invention of "Time", problems(a lot of them) were there. Like if your watch showed 10:20 and your friends watch showed 10:27 who was right? In the 19th century an English woman named Ruth Belville saw this as an opportunity and started syncing people's watch to hers telling them her time was correct.

We didn't really needed timezones before that because there wasn't any need for it. People couldn't travel to the other half of the world back then and certainly couldn't communicate with people in other time zones.Time standardising became a thing when trains started as it became very annoying to change your watch's time every few minutes.

To combat this the US President Chester A. Arthur called a conference of 26 countries.Finally on October 22nd, 1884 the world was put into timezones in 1 hour deviations and the Royal Observatory in Greenwich, England was set as the reference.
