About Timestamp Converter

Timestamp Converter converts Unix timestamps (epoch time) to readable dates and dates back to timestamps. It detects whether a timestamp is in seconds or milliseconds and shows the result in your local time zone, in UTC, in ISO 8601 and as relative time ("3 hours ago").

A live clock shows the current Unix time, and "Use current time" fills in now. It is an everyday tool for reading logs, database values and API responses. It runs entirely in your browser, so nothing you paste is uploaded.

How to use Timestamp Converter

  1. Enter a Unix timestamp to get the date — or a date/time to get the timestamp.
  2. Read the local, UTC, ISO and relative results.
  3. Copy the value you need.

Key features

  • Seconds and milliseconds detected automatically
  • Local time, UTC, ISO 8601 and relative time
  • Live current-epoch clock
  • Date → timestamp conversion

Example

The same moment shown in UTC and in other time zones.

When to use Timestamp Converter

  • Reading epoch times in logs, databases and API responses.
  • Converting a deadline into a Unix timestamp for code or a config file.
  • Checking what time a server event happened in Indian Standard Time.

Tips and common problems

  • 10 digits are seconds, 13 digits are milliseconds.
  • Unix time is the same everywhere; only the displayed local time changes with the time zone.
  • IST is UTC + 5:30, so a midnight UTC event appears at 5:30 AM in India.

Frequently asked questions

The number of seconds since 1 January 1970, 00:00 UTC. It is the same everywhere in the world at a given moment, regardless of time zone.
