Mtime — Monotonic wall-clock time for OCaml

Mtime has platform independent support for monotonic wall-clock time in pure OCaml. This time increases monotonically and is not subject to operating system calendar time adjustments. The library has types to represent nanosecond precision timestamps and time spans.

The additional Mtime_clock library provide access to a system monotonic clock.

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