Unix Timestamp Converter — free online tool
Debuggers and log files use Unix epoch seconds; convert to local date-time or the reverse when reading server logs.
When to use Unix Timestamp Converter
Translate Unix epoch values from logs into human dates (and back) while debugging.
Cross-check anything that affects money or health with a qualified professional or official source.
What Unix Timestamp Converter does not do
Does not parse ISO time zones with DST rules beyond what the browser Date object provides. Not a cron scheduler.
How to use Unix Timestamp Converter
- Paste a Unix epoch in seconds or milliseconds into Unix Timestamp Converter.
- Or pick a local date-time to see the equivalent epoch.
- Convert and read both human-readable and epoch forms side by side.
- Note whether your log source uses seconds or milliseconds before comparing.
Practical tips
- Confirm whether your source uses seconds or milliseconds—an extra three digits shifts the date by millennia.
- Epoch time is UTC; convert to your local zone before quoting a time to a colleague.
- Handy for reading server logs where everything is stored as Unix seconds.
Example
Convert 1700000000 seconds to a local date when reading nginx logs.

Limitations
Seconds vs milliseconds matter—wrong unit is off by 1000×. Uses your browser’s local timezone display.
