A Unix Timestamp Converter translates between Unix timestamps — the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC, known as the Unix Epoch — and human-readable date/time strings. Unix timestamps are the universal language of date and time in computing; virtually every programming language, database, API, and operating system uses them internally.
Storing time as a single integer has enormous advantages over storing a formatted date string:
Server and application logs: Every log line has a Unix timestamp. When debugging a production incident, converting the timestamp of an error entry to a local time is the first step.
Database records: created_at, updated_at, and deleted_at columns are typically stored as Unix timestamps or UTC datetime values. Developers frequently need to check whether a specific record was created before or after a particular event.
JWT tokens: The exp (expiration) and iat (issued-at) claims in JWT tokens are Unix timestamps. A JWT decoder or this converter reveals exactly when a token was issued and when it expires.
API responses: REST and GraphQL APIs from Twitter, GitHub, Stripe, and most other services return event timestamps as Unix values. Converting them to readable dates is necessary for displaying them in a UI or interpreting them in logs.
Cron and scheduling: Scheduled task systems often express next-run times as Unix timestamps.
