type t = private {
  1. s : int64;
  2. ns : int;
}

Signed/directional span of time expressed as a tuple of (s, ns)

  • s carries the sign of the span
  • ns carries the unsigned offset

The actual span represented is defined as s * 10^9 + ns in nanosecond, regardless of the sign of s

Order is defined using lexicographical order, i.e. lt x y iff. x.s < y.s || (x.s = y.s && x.ns < y.ns)

val ns_count_in_s : int
val ns_count_in_s_float : float
val zero : t
val make : ?s:int64 -> ?ns:int -> unit -> t

s defaults to 0L, ns defaults to 0

ns may be negative, and is normalized during construction

Interpretation of provided input is still s + ns, i.e. if you wish to represent "negative (1 second and 500 nanosecond)", then the call could look like make ~s:(-1L) ~ns:(-500)
