- In the context of "transitive|computing": To record the date and time of (an event, etc).
A timestamp is a sequence of characters, denoting the date and/or time at which a certain event occurred. This data is usually presented in a consistent format, allowing for easy comparison of two different records and tracking progress over time; the practice of recording timestamps in a consistent manner along with the actual data is called timestamping.
Timestamps are typically used for logging events, in which case each event in a log is marked with a timestamp. In filesystems, timestamp may mean the stored date/time of creation or modification of a file.
StandardizationThe International Organization for Standardization (ISO) has defined ISO 8601 which standardizes timestamps.
