module Monotonic : sig ... end

Monotonic time is time since boot (dom0 or domU, depending on platform). * Unlike Clock.time, it does not go backwards when the system clock is * adjusted.

val restart_threads : (unit -> [ `Time ] Monotonic.t) -> unit

restart_threads time_fun restarts threads that are sleeping and whose wakeup time is before time_fun ().

val select_next : unit -> [ `Time ] Monotonic.t option

select_next () is Some t where t is the earliest time when one sleeping thread will wake up, or None if there is no sleeping threads.

val sleep_ns : int64 -> unit Lwt.t

sleep_ns d Block the current thread for n nanoseconds.
