Quick Reference

Seconds — 10 digits (Unix time). Range: 1970-01-01 … 2286-11-20.

Milliseconds — 13 digits. JavaScript Date.now(), Java System.currentTimeMillis().

Microseconds — 16 digits. Python time.time_ns() // 1000, C gettimeofday().

Nanoseconds — 19 digits. Go time.Now().UnixNano(), C++ std::chrono::system_clock, PTP timestamps, CME Globex, Databento ts_event.

Picoseconds — 22 digits. High-resolution timing hardware, TAI pico-epoch.


FIX UTCTimestampYYYYMMDD-HH:MM:SS.sss. FIX 4.2+ protocol timestamp format.

PTPseconds.nanoseconds. IEEE 1588 Precision Time Protocol.

NTP — Seconds since Jan 1, 1900. Add 2,208,988,800 to convert to Unix.

GPS — Seconds since Jan 6, 1980. No leap seconds (monotonic).

TAI — UTC + 37 leap seconds (as of 2017-01-01). Monotonic atomic time.
