Time.t is precise to approximately 0.24us in 2014. If to_span converts to the closest Time.Span.t, we have stability problems: converting back yields a different t, sometimes different enough to have a different external representation, because the conversion back and forth crosses a rounding boundary.

To stabilize conversion, we treat Time.t as having 1us precision: to_span and of_span both round to the nearest 1us.

Around 135y magnitudes, Time.Span.t no longer has 1us resolution. At that point, to_span and of_span raise.

val to_int63_ns : t -> Core_kernel.Int63.t

Fast, implemented as the identity function.

val of_int63_ns : Core_kernel.Int63.t -> t

Somewhat fast, implemented as a range check.

val to_int_ns : t -> int

Will raise on 32-bit platforms with spans corresponding to contemporary now. Consider to_int63_ns instead.

val of_int_ns : int -> t
val to_proportional_float : t -> float

The only condition to_proportional_float is supposed to satisfy is that for all t1, t2 : t: to_proportional_float t1 /. to_proportional_float t2 = t1 // t2.

Span.Option.t is like Span.t option, except that the value is immediate on architectures where Int63.t is immediate. This module should mainly be used to avoid allocations.
