An overflow-safe, high-performance datetime library providing leap-second-correct nanosecond precision across UTC, GPST, and relativistic time-scales. Flight-proven in lunar and deep-space missions.
Find the next leap second using IERS-OP web service.
Public UTC is a free, no-log public NTP time service with Network Time Security (NTS, RFC 8915). Use smear.public-utc.com (recommended) or leap.public-utc.com. IPv4 and IPv6.
A high-performance Python library for parsing and analyzing the IANA Time Zone Database (tzdb). Built for production use with smart caching, minimal dependencies, and a practical API.
Faithful, memory-safe Rust port of upstream leapseconds.awk — generates the zic 'leapseconds' source from NIST/IERS leap-seconds.list, byte-identical to the awk oracle.
A python library for handling precise date/times, virtually infinitely far into the past and future, including support for leap seconds and partial support for timezones.
