Timestamp

Noun · Development

Definitions

  1. A value representing a specific point in time, typically stored as seconds or milliseconds since the Unix epoch (January 1, 1970 UTC) or as an ISO 8601 string — used for ordering events, auditing changes, and computing durations.

    In plain English: A recorded date and time that marks exactly when something happened.

    Example: "Always store timestamps in UTC and convert to the user's timezone at display time — mixing timezones in the database is a nightmare."
