Module Time_ns

module Time_ns: sig .. end
An absolute point in time, more efficient and precise than the float-based Time, but representing a narrower range of times.

This module represents absolute times with nanosecond precision, approximately between the years 1823 and 2116 CE.

NOTE: you should normally default to using Time instead of this module. The reasons are:

Some reasons you might want want to actually prefer Time_ns.t in certain cases:

All in all, it would have been nice to have chosen Time_ns.t to begin with, but we're unlikely to flip everything to Time_ns.t in the short term (see comment at the end of time_ns.ml).

pause span sleeps for span time.
val interruptible_pause : Span.t -> [ `Ok | `Remaining of Span.t ]
interruptible_pause span sleeps for span time unless interrupted (e.g. by delivery of a signal), in which case the remaining unslept portion of time is returned.
val pause_forever : unit -> Core_kernel.Std.never_returns
pause_forever sleeps indefinitely.
