A unified time framework of geoscience knowledge (IMAGE)
Caption
The unified time framework of geoscience knowledge consists of three components: chronology, calendar, and timing. Chronology serves as the foundation of the time framework and provides methods for establishing the origin and naming of eras. The calendar is used to calculate the years, months, and days. Timing is to represent a specific time by considering the timing standards and their offsets from the world timing standard.
