The Caml Hump: Oclock

Precise POSIX clock library for Ocaml. This library uses the clock_gettime(2) family of functions, to get precisions from below the milliseconds upto the nanoseconds depending on the platform (system and CPU). It lets you measure time from the real-time clock, monotonic clocks, or CPU-time clocks of the current process, of a remote process, or of a thread.
