How to Use This Developer Tool

  1. Read the current time in seconds, milliseconds, microseconds, and nanoseconds.
  2. Click any value to copy it.
  3. Paste a timestamp into the input — the converter detects the precision and shows UTC and local dates.
  4. Click Now to refresh the live timestamp.

What Is an Epoch Converter?

Unix timestamps count from 1970-01-01 00:00:00 UTC, but different systems pick different precisions: classic Unix uses seconds, JavaScript uses milliseconds, microservice telemetry often uses microseconds, and high-resolution clocks reach nanoseconds. Matching the precision matters — pass a millisecond value into a function expecting seconds and you'll be off by a factor of 1000.

The converter shows the current time at all four precisions, copies any of them with one click, and converts a user-entered timestamp back to UTC and local human-readable dates. Precision is auto-detected from the magnitude of the input so you can paste straight out of a log line without guessing.

Frequently Asked Questions

What's the difference from Unix Timestamp Converter?
Epoch and Unix timestamp converters are often the same — both convert seconds since 1970-01-01 UTC to dates. This one also shows millisecond, microsecond and nanosecond precision.
What is the current epoch time?
It changes every second. Use the 'now' button to capture the live value.
When does the 32-bit overflow happen?
January 19, 2038 for signed 32-bit. Use 64-bit values or milliseconds for long-term safety.
