Can you summarize and write a brief synopsis on the following:

"Before we discuss history, we must discuss time, for that is the canvas on which history occurs. Unfortunately, although we are used to thinking in terms of days and months and years, those are Earth-specific terms. On a different planet, Earth-centric periods will have little meaning, and its own rotational and revolutionary periods and those of its satellites will be more useful. Then we throw in the fact that wormholes connect across both space and time, so that a trip from Žemyna to Homestead will take you hundreds of years into the future, and the return trip takes you hundreds of years back in time. And this is even before we throw in how time slips between planets when considering relativistic time dilation due to different speeds and gravitational potentials.

Fortunately, all the weirdness of different time rates and going backward and forward in time can be ignored by the average person. This is because you never need to go from Žemyna to Homestead, or back, across the vast gulfs of interstellar space. You just take the wormhole between them. All you ever need to worry about is the coordinate frame that goes across the wormhole. When considering this reference frame, you're not hopping all over the place in time. If it takes ten minutes to cross the Žemyna-Homestead wormhole, when you get to Homestead the clocks will read ten minutes later than they did when you left Žemyna. By coordinating their time-keeping across the wormhole network, Žemyna and Homestead and all the other worlds of the Verge can agree on a common time to coordinate their activities. This is all travelers ever need to worry about, and they can then ignore all the relativistic weirdness.

But you still have to deal with each planet with its own day/night cycles and yearly periods that are incommensurate with those of the other worlds. Early on, the coordinating bodies of Earth introduced Coordinated Network Time (CNT) as the official time system to use across interstellar space. This time measurement system divorces itself from traditional Earth-centric days and years and uses the base SI unit of time – the second – with metric prefixes to give a planet-agnostic standard.

A time in CNT is represented as, for example, 6G 311M 347k 211.19s CNT - meaning 6 billion, 311 million, 347 thousand, 211.19 seconds from time zero. In everyday conversation, 1 gigasecond (Gs) is called a "gig", 1 megasecond (Ms) is a "meg", and 1 kilosecond (ks) is a "click". Times before time zero CNT are represented with negative numbers. This system avoids complications like leap years, a missing year when going from BC to AD, figuring out how many days hath September, and other such nuisances. The current time in the Verge is nominally set at 6G 820Ms CNT.

When The Bump in the Night struck, the Verge lost contact with the standards institutes on Earth that kept and distributed official time. For a time, the worlds of the Verge kept their own versions of CNT with the clocks that they had. Before long, a standards committee was established, and a new CNT was set up for the Verge Republic network.

Each individual planet also uses its own time system for its internal affairs. These are based on time units more convenient to that planet - the periods of rotation (days) and revolution (years) of the planet and of its natural satellites (months). For periods of time shorter than a day, some worlds have adopted metric time but the majority use hours and minutes. Most people can convert between metric and traditional time without much difficulty. When on metric time and no convenient planetary cycle approximates the Human diurnal cycle, the default is to use 100 kiloseconds as a "diurnal" - the time of the Human sleep-wake cycle. Although a bit longer than a terrestrial day, most Humans and Pannovas can easily adapt to it and, in fact, often appreciate the little bit of extra time they have before going to bed (or waking up).

Gummis and Mants each have their own methods of time-keeping. The Gummi base unit of time is approximately 5.7 seconds and is counted in base 8. Mants have a baroque system of time-keeping that other sapients have a hard time keeping straight."
