What does timestamping mean?
Timestamping is the practice of associating a precise date and time with an event or digital item, usually by adding machine-readable metadata. It is common in computing: file systems and databases timestamp records, messaging systems record when content was sent, and transaction systems preserve the order and timing of events. In digital-security and legal contexts, timestamping may mean obtaining a trusted, cryptographically verifiable assertion that a document or message existed at a particular time. Such a timestamp can support evidence of sequence and integrity, although its legal value depends on applicable rules and the reliability of the provider. The word is usually uncountable in general use, while countable uses exist when referring to separate instances. It is technical but neutral in tone, and the related verb “timestamp” means to add such a date-and-time record. Overall, timestamping converts the broad idea of “when” into a specific, shareable, and often auditable fact.

Where does timestamping come from?
Timestamping is a modern English formation based on the compound verb “timestamp,” which combines “time” with “stamp.” Both components are inherited English words of Germanic origin: “time” denotes a period or point in time, while “stamp” means to mark or impress something. The compound became especially useful in modern record-keeping and computing, where events are marked with their date and time.
