online timestamp converter
Convert Unix timestamp to date and vice versa
Quick start: Timestamp Converter in 3 steps
- Paste a Unix timestamp or pick a date/time
- Confirm seconds vs milliseconds
- Read local and UTC output, then copy the format you need
Timestamp Converter: curated examples
- •Example: convert JWT `exp` to a readable time to check expiry.
- •Example: interpret a 13-digit ms stamp from logs against server timezone.
About Timestamp Converter
Convert Unix timestamps in seconds or milliseconds to and from dates, with local-time and UTC views. The page also provides the current time and batch conversion for logs and API fields.
The common failure is reading a 13-digit millisecond value as a 10-digit seconds value, so confirm the unit first.
How Timestamp Converter works
For scripts, migrations, and automated checks, use standard-library time functions or date/jq. For one number under investigation, a page that shows both its unit and time zone makes a mistaken reading less likely.
A timestamp carries no time zone. Compare UTC first and record whether input is seconds or milliseconds; otherwise an eight-hour or thousandfold difference is often mistaken for a service failure.
Why use Timestamp Converter on WoDeTool
WoDeTool keeps Timestamp Converter, related utilities, clipboard detection, and pipelines together, so you can work through JSON, JWT, and Diff in one workspace.
Use Smart Clipboard on the home page to auto-detect pasted JSON, Base64, or JWT and jump to Timestamp Converter. Save a tool pipeline to chain Timestamp Converter with related utilities. Read our guides for real-world workflows.
Common use cases
- •Read an API expiry: Convert 1710000000 to check whether an expires_at response is expected.
- •Locate an incident window: Turn 1710000000123 from a log into UTC and local time to align it with an alert.
- •Check a database field: Inspect an integer created_at to see whether milliseconds were written where seconds were expected.

Frequently asked questions
- Is Timestamp Converter free to use?
- Yes. Timestamp Converter on WoDeTool is completely free with no sign-up required. Open the page and start using it immediately.
- Seconds vs milliseconds — how to tell?
- 10 digits ≈ seconds (1718123456); 13 digits ≈ milliseconds (1718123456000). Wrong unit shifts dates by ~1000×.
- What timezone is used?
- Results show local time and UTC. API logs usually store UTC seconds — mind timezone when comparing.
