Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Ephemeris Time | Statement: [Terrestrial Time, successorOf, Ephemeris Time]

Target entity: Ephemeris Time
Context triple: [Terrestrial Time, successorOf, Ephemeris Time]

• A. Terrestrial Time
  Terrestrial Time is a modern astronomical time standard used for precise calculations of planetary motion and ephemerides, defined in relation to atomic time rather than Earth's rotation.
• B. Coordinated Universal Time
  Coordinated Universal Time (UTC) is the primary global time standard by which the world regulates clocks and time, serving as the basis for most civil time zones.
• C. Greenwich Mean Time
  Greenwich Mean Time is the mean solar time at the Royal Observatory in Greenwich, London, historically used as the world’s primary reference for timekeeping and the basis for Coordinated Universal Time (UTC).
• D. International Atomic Time
  International Atomic Time is a high-precision time standard based on the combined output of atomic clocks worldwide, serving as the fundamental reference for modern civil and scientific timekeeping.
• E. Metonic cycle
  The Metonic cycle is a 19-year astronomical period after which the phases of the Moon recur on the same days of the solar year, forming the basis for many lunisolar calendars.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Ephemeris Time
Triple: [Terrestrial Time, successorOf, Ephemeris Time]

Ephemeris Time is a former astronomical time standard based on the orbital motion of the Earth around the Sun, used to provide a uniform measure of time before being replaced by more precise atomic-based scales.
