Module Time_ns

module Time_ns: sig .. end
Time represented as an Int63.t number of nanoseconds since the epoch.
module Span: sig .. end

Note that we expose a sexp format that is not the one exposed in Core.

val next_multiple : ?can_equal_after:bool ->

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.
