Current Unix Timestamp

View the browser wall-clock Unix timestamp live. Microsecond and nanosecond values are scaled from the millisecond wall clock rather than claimed as true sub-millisecond measurements.

—Nanoseconds*

—* Microsecond/nanosecond displays are scaled from the browser millisecond wall clock; they are not claims of true sub-millisecond clock resolution.

Unix/POSIX time is based on seconds since the 1970-01-01 UTC epoch. Browser date rendering uses JavaScript Date/Intl; sub-millisecond epoch arithmetic is preserved with BigInt where the tool exposes it.
