Timestamp

Common card · No. 251194

A timestamp is a sequence of characters or encoded information identifying when a certain event occurred, usually giving the date and time of day, sometimes accurate to a small fraction of a second. Timestamps do not have to be based on some absolute notion of time, however. They can have any epoch, can be relative to any arbitrary time, such as the power-on time of a system or some arbitrary time in the past. A distinction is sometimes made between the terms datestamp (DS), timestamp (TS) and date-timestamp (DTS): Datestamp: A date, for example 2026-11-04 according to ISO 8601 Timestamp: A time of day, for example 00:57:23 (using the 24-hour clock) Date-timestamp: Date and time, for example 2026-11-04T00:57:23 (ISO 8601)
