chronogram:
1. A phrase, sentence, or inscription, in which certain letters (usually distinguished by size or otherwise from the rest) express by their numerical values a date or epoch.
2. An inscription, sentence, or phrase in which certain numeral letters, usually made especially conspicuous to express a particular date or epoch on being added together; as in: Man of sCience and huManity, Bertrand RusselL’s eXample gIves life eXtra meaning = MCMLXIX or 1969, the year of Bertrand Russell’s death.
3. In horology, the record produced by an instrument that records time intervals, such as the duration of an event.
chronograph:

chronologer:
One who studies chronology, one who investigates the date and order in time of events; a chronologist.
chronological:
1. Arranged in the order of time sequence.
2. Relating to or dealing with chronology.
3. Chronological age refers to a person's actual age as calculated from birth, as opposed to any age classification based on the rate of mental development.
Time goes, you say? Ah no!
Alas, Time stays, we go.
—Austin Dobson (1840-1921), British author
chronology:
1. The science of computing and adjusting time or periods of time, and of recording and arranging events in the order of time; computation of time, assignation of events to their correct dates.
2. A chronological table, list, or treatise.
3. The scientific study of time and the sequence of events.
chronomancy, chromomantic:
Divination to determine the favorable time for some action, formerly practiced especially in China.
chronometer:
1. In horlology, the time of day as indicated by a chronometer set to Greenwich Mean Time.
2. An instrument for measuring time; specifically applied to time-keepers adjusted to keep accurate time in all variations of temperature. They differ from watches by having a more perfect escapement and a compensation balance, and are used for determining longitude at sea, and for other exact observations.
chronometry:
The art or science of accurately measuring time; or the measurement of intervals of time.
chronometric:
Any method of dating that relies on chronological measurements; such as, calendars, radiocarbon dates, etc.
chronometric encoder:
In electronics, an encoder that converts information into digital form by counting electrical pulses.
chronomyometer:
An instrument for measuring the chronaxy of muscle.
chrono-oncology:
An anticancer treatment based on the timing of drug administration.
A branch of chronobiology concerned with the effects of drugs upon the timing of biological events and rhythms, and the relation of biological timing to the effects of drugs.
1. A device that generates standard time signal pulses from a clock or other timing mechanism.
2. An apparatus for the distribution of electric time-signals.
A paraphilia in which sexual satisfaction depends on the age of the partner; most frequently, the partner must be of a greatly different age than the subject (chronophilic disparity). The term includes ephebophilia (adolescents are the sexual object), gerontophilia (the partner must be older, of parental or grandparental age), nepiophilia (infants), and pedophilia (juveniles).
A morbid or neurotic fear of the duration or immensity of time.
A photograph taken as one of a series for the purpose of showing successive phases of a motion.
Employing intervals of time with a fixed significance (as in a system of signaling) by exposing visual objects or sounding audible signals for selected intervals of time.
1. A species which is represented in more than one geological time horizon.
2. The successive species replacing each other in a phyletic lineage which are given ancestor and descendant status according to the geological time sequence.
Distortion or confusion of the sense of time; as for dates, seasons of the year, times of day, and overestimation or underestimation of the duration of time.
The treatment of certain sleep disorders by capitalizing on the natural phase delay in adults; the bedtime is successively advanced by one to several hours each day until the individual can retire, sleep, and arise at appropriate times.
A timepiece so constructed as to exaggerate the effect of changes of temperature upon its rate and used to indicate mean temperature.
1. Modification of the rate of a periodic movement, e.g., the heartbeat, through some external influence.
2. An orientation response due to age; used particularly with reference to the movement of leaves in plants.
