Random Timestamp Generator
Generates a random ISO-8601 UTC timestamp between 2020-01-01 and 2030-12-31 — a test value, not a real event's recorded time.
What this generator does
Produces a machine-readable timestamp for seeding logs, database columns and API fixtures.
How to use this tool
- Press generate for a random timestamp.
Worked examples
- Format
- 2026-08-09T14:37:52Z — ISO 8601, UTC
Common use cases
- Placeholder timestamps for mock data
- Testing date-parsing code
- Sample data for documentation
How this generator works
A moment is drawn within your range and shown as a Unix timestamp in seconds, as milliseconds, and in ISO 8601 form. All three describe the same instant, and showing them together is the point: a value that is out by a factor of a thousand is invisible on its own and obvious next to its neighbours.
Limitations and good to know
- Always UTC, so a test that assumes local time will need to convert it.
- Seconds and milliseconds are the two common Unix conventions and they are trivially confused. A seconds value read as milliseconds lands in January 1970.
- The ISO form is in UTC, marked with a trailing Z. A local-time reading of it will be wrong by your offset.
- Timestamps beyond 2038 exceed what a signed 32-bit seconds field can hold, and older systems will wrap rather than refuse.
A randomly generated test value — never a real event's recorded time.
