Ptime has platform independent POSIX time support in pure OCaml. It provides a type to represent a well-defined range of POSIX timestamps with picosecond precision, conversion with date-time values, conversion with RFC 3339 timestamps and pretty printing to a human-readable, locale-independent representation.

The additional Ptime_clock library provides access to a system POSIX clock and to the system's current time zone offset.

Ptime is not a calendar library.

Ptime has no dependency. Ptime_clock depends on your system library or JavaScript runtime system. Ptime and its libraries are distributed under the ISC license
