This is a list of Global Boundary Stratotype Sections and Points.Since 1977, Global Boundary Stratotype Sections and Points (abbreviated GSSPs) are internationally agreed upon reference points on stratigraphic sections of rock which define the lower boundaries of stages on the geologic time scale.
In the United Kingdom, non-departmental public body (NDPB) is a classification applied by the Cabinet Office, Treasury, the Scottish Government, and the Northern Ireland Executive to public sector organisations that have a role in the process of national government but are not part of a government department.

The BP scale is sometimes used for dates established by means other than radiocarbon dating, such as stratigraphy. [5] [6] This usage differs from the recommendation by van der Plicht & Hogg, [7] followed by the Quaternary Science Reviews, [8] [9] both of which requested that publications should use the unit "a" (for "annum", Latin for "year") and reserve the term "BP" for radiocarbon estimations.
The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks).
Time scale may refer to: Time standard, a specification of either the rate at which time passes, points in time, or both; A duration or quantity of time: Orders of magnitude (time) as a power of 10 in seconds; A specific unit of time; Geological time scale, a scale that divides up the history of Earth into scientifically meaningful periods
The agreement guarantees a market for the utility-scale solar facility's energy for a fixed term of time. [4] (Residential solar systems are not considered utility-scale). The size of a utility-scale facility can vary. For example, some utility-scale facilities provide only enough power for a few hundred average homes. Others offer a lot more ...
The former uncorrected time scale continues to be published under the name EAL (Échelle Atomique Libre, meaning Free Atomic Scale). [ 14 ] The instant that the gravitational correction started to be applied serves as the epoch for Barycentric Coordinate Time (TCB), Geocentric Coordinate Time (TCG), and Terrestrial Time (TT), which represent ...
