Conversor de marcas de tiempo
Convierte epoch Unix a fechas y viceversa, con reloj en vivo
Current time

Timestamp → date
Enter a Unix value. Values with absolute magnitude ≥ 100,000,000,000 are treated as milliseconds; smaller integers as seconds.
Date → timestamp
Fill local date/time fields, or paste an ISO 8601 string (ISO takes precedence when non-empty).
Convert Unix timestamps to dates and back, with a live clock
Logs, databases, and APIs love Unix timestamps; humans don't. A timestamp converter handles both directions — epoch seconds or milliseconds in, ISO and human-readable dates out, plus the reverse — and shows the current time as a live clock so you can grab a fresh value while debugging.
Use the converter when you need to
Read a timestamp from a log line
Paste epoch seconds or milliseconds and instantly see the date in your local timezone and UTC.
Construct a test value for an API
Build a date in human form and copy the corresponding Unix timestamp for use in a request body.
Check token expiry by hand
Decode a JWT, copy the exp claim, and convert it to a real date to confirm whether the token is expired.
How to convert timestamps quickly
- 1
Paste a Unix timestamp or pick a date in the form fields.
- 2
View the converted ISO string, local date, and UTC date in real time.
- 3
Use Now, Start of today, or Start of year buttons for common reference points.
Keep going
Generate IDs
Pair timestamps with UUIDs when building traceable records or request IDs.
Decode JWT tokens
Read the iat, nbf, and exp claims and convert them back to dates with this tool.
Send a test request
Plug a fresh timestamp into an API request body and verify the endpoint behavior.
Format JSON with timestamps
Clean up payloads that include epoch fields before pasting them somewhere else.
Common timestamp workflows
Convert the epoch in the log to local time to align with what a customer reported.
Confirm a recently issued JWT's exp claim corresponds to the lifetime your auth provider configured.
Generate a known epoch value and use it across tests for deterministic results.

Puedes usar ambos. Los números enteros con valor absoluto por debajo de 100,000,000,000 se interpretan como segundos; magnitudes mayores se interpretan como milisegundos. La salida siempre muestra segundos y milisegundos.
Los campos numéricos de año/mes/día/hora/minuto/segundo se interpretan en tu zona horaria local. Las cadenas ISO se parsean según las reglas estándar de JavaScript Date (se aplican Z u offsets cuando están presentes).
Now rellena el instante actual. Start of today establece la medianoche local del día actual. Start of year establece el 1 de enero a las 00:00:00 en hora local del año en curso.
El reloj en vivo se actualiza cada segundo para que puedas copiar un timestamp Unix reciente mientras pruebas APIs o revisas logs.
