A division of geologic time less than a period and greater than an age.
A subdivision of geologic time that is longer than an age but shorter than a period. The Tertiary Period is divided into five epochs. From most recent to oldest they are: Pliocene, Miocene, Oligocene, Eocene and Paleocene.
A division of geologic time; a subdivision of a period. Example: Pleistocene epoch. View timeline of geologic events.
Geologic time unit that is shorter than a period.
subdivision of a geological period of time
A subdivision of a geologic period, often chosen to correspond to a stratigraphic sequence. Also used for a division of time corresponding to a paleomagnetic interval.
An interval of geologic time representing the largest subdivision of a period.
An interval of geologic time; a division of a period. (Example: Pleistocene Epoch).
a period of time characterized by certain notable events.
a period marked by distinctive character or reckoned from a fixed point or event
a unit of geological time
a convenient time interval, usually equal to one page of record
an extended period of time marked by a memorable series of events," says Scott Ryles, the investment bank's president and chief executive officer
a particular period of time marked by distinctive features, events, etc
a period that begins either when the receiver enters the SLOW-START or CONGESTION-AVOIDANCE state or at the beginning of the transmission session
an interval of geologic time smaller than a period
Eh-poc Time within a period. 359
A period of history; in Unix, "The Epoch" begins at 00:00:00 UTC January 1, 1970. This is considered the "dawn of time" by Unix and Unix-like operating systems, and all other time is calculated relative to this date.
events (or sections of a tank block) that are associated with the tank's timeline. Epoch events can be scalar variables including triggered scalars, data lists, and their associated secondary tags. Epoch events can be used by other OpenEx applications such as OpenScope and OpenBrowser to sort and display tank data.
An important period of time, an era, or the beginning of same.
geochronologic](a) A geologic-time unit longer than an age and shorter than a period, during which the rocks of the corresponding series were formed. (b) A term used informally to designate a length (usually short) of geologic time.
n. The time and date corresponding to 0 in an operating system's clock and time-stamp values. For most versions of the UNIX operating system, the epoch is 00:00:00 GMT, 01 January 1970. System time is measured as the number of seconds past the epoch.
Measurement interval or data frequency, as in making observations every 15 seconds. "Loading data using 30-second epochs" means loading every other measurement.
A timestamp that identifies directory replicas as being part of the same set.
a period of time; distinguishable by a particular series of events..
An interval of geologic time longer than an Age and shorter than a Period.
The fourth-longest phase of geologic time, shorter than an era and longer than an age or a chron. The current epoch is the Holocene, which began about 0.01 Ma (10,000 years) ago.
An epoch is an individual time period for which a report has been generated. Epochs can be days, weeks, months, quarters, or years, depending on the Daily Reports (daily), Weekly Reports (weekly), Monthly Reports (monthly), Quarterly Reports (quarterly) and Annual Reports (annual) settings. The Summary Reports (summary) report can also be thought of as a single epoch spanning the entire time range over which the program has been used.
The date used as the “beginning of time†for timestamps. Time values in Unix systems are represented as seconds since the epoch, with library functions available for converting these values into standard date and time formats. The epoch on Unix and POSIX systems is 1970-01-01 00:00:00 UTC. See also “GMT†and “UTC.
A division of geologic time shorter than a period.
A division of a geologic period; it is the smallest division of geologic time, lasting several million years.
A division of a geologic period, which is in turn a division of an era. The Pleistocene is an epoch.
1. The formal geochronologic unit, longer than a geologic age and shorter than a geologic period, during which the rocks of the corresponding series were formed (from Glossary of Geology 1997). 2. A term used informally to designate a length (usually short) of geological time, for example, glacial epoch. 3. In paleomagnetism, a date to which measurements of a time-varying quantity are referred, for example, "a chart of magnetic declination for epoch 1965.0," or informally as a magnetic polarity epoch. Magnetic polarity refers to whether the geomagnetic field was like it is today (normal polarity) or whether the north and south poles are reversed from their present configuration (reversed polarity).
