Horometrical is a rarely used word that means pertaining to measuring time. However, there are several synonyms that have almost the same meaning. For instance, the word "chronometric" (related to the measurement of time), can replace horometrical in most contexts. "Temporal" (pertaining to time) is also another synonym that can be used in place of horometrical. Other similar terms include "chronological" (arranged in order of time) and "chronograph" (a device used to measure time). Finally, "horological" (related to the study of time and timekeeping devices) is another synonym that can be used in place of horometrical.
