Unix Timestamp Converter
Convert Unix timestamps to dates and back — seconds to nanoseconds, any IANA time zone, a relative readout and a live clock, entirely in your browser.

The time zone applies to both directions: the zoned row below and the date → timestamp block.
| UTC (ISO 8601) | |
|---|---|
| RFC 2822 (UTC) | |
| Selected time zone | |
| Relative |
The unit is detected from the number's magnitude and can be overridden; a fraction like 1700000000.5 is read as seconds with millisecond precision.
Date → timestamp

With no offset the time is read in the selected time zone; Z, +01:00 and +0100 fix it explicitly.
