eventtids

Eventtids is a term used in Danish- and Norwegian-language texts to denote the exact moment at which an event occurs, as captured by a timestamp. It refers to clock time or calendar time of occurrence, in contrast to other time notions such as processing time (when the event is observed by a system) or reporting time (when the data is recorded or published). In practice, eventtids are stored as a timestamp, often in ISO 8601 format and with a defined time zone.

In data analysis, eventtids are central to time-to-event or survival analysis, where the response variable is the duration from a defined origin to the occurrence of an event (for example, failure, relapse, or purchase). Eventtids enable aligning observations across individuals or units and allow censoring when the event has not yet occurred by the end of the observation window.

In computer science and event-driven systems, eventtids underpin log analytics, stream processing, and auditing, where each event carries a time-of-occurrence attribute that drives ordering and windowed computations.

Key data quality considerations include time zone handling, clock synchronization, timestamp precision, and missing or ambiguous times. Analysts must address censoring, left-truncation, and potential delays between occurrence and observation.
