Depends what you are looking at.
Usually hours.
Midnight
absolute time is time measured in definite periods such as minutes, days, and years
Time has no length, width or thickness.
time! (hours, minutes, years, months, days, seconds, milliseconds)
The Precambrian Time
The measurement of Earth's history divided into time periods is called the geological time scale. It is divided into eons, eras, periods, epochs, and ages, with each unit representing a significant change in Earth's geological and biological history.

The Precambrian time
how different parts of earths history compare to the whole world
The Devonian Period was from 416 MYA - 360 MYA.
We were left along time A ago , but today we can tell you A allot about earths history . What am I ?
So you can understaned it much more better and think about it!
