Decode hexadecimal Unix epochs

Logs, firmware dumps, and reverse-engineering notes often store Unix time as hexadecimal instead of decimal seconds. Paste a hex value (with or without a 0x prefix) to see the matching calendar date, or pick a datetime to generate the hex encoding.

For decimal Unix timestamps, use the Epoch Unix Timestamp Converter. For Chrome history microsecond values, try the WebKit Chrome Timestamp Converter.

Frequently Asked Questions

Are values interpreted as seconds or milliseconds?

Hex strings longer than 10 digits are treated as millisecond epochs and converted to seconds automatically. Shorter values are read as Unix seconds.
