Module Time_ns

Time represented as an Int63.t number of nanoseconds since the epoch.

val epoch : t

Unix epoch (1970-01-01 00:00:00 UTC)

val min_value : t
val max_value : t
val now : unit -> t
val add : t -> Span.t -> t
val sub : t -> Span.t -> t

val to_int63_ns_since_epoch : t -> Core_int63.t
val of_int63_ns_since_epoch : Core_int63.t -> t
val to_int_ns_since_epoch : t -> int

Will raise on 32-bit platforms. Consider to_int63_ns_since_epoch instead.

val of_int_ns_since_epoch : int -> t
val next_multiple : ?can_equal_after:bool -> base:t -> after:t -> interval:Span.t -> unit -> t

next_multiple ~base ~after ~interval returns the smallest time of the form:


      time = base + k * interval

where k >= 0 and time > after. It is an error if interval <= 0.

Supplying ~can_equal_after:true allows the result to satisfy time >= after.
