val typerep_of_t : t Typerep_lib.Std.Typerep.t
val typename_of_t : t Typerep_lib.Std.Typename.t

String and sexp output takes the form 'HH:MM:SS.sssssssss'; see Core_kernel.Ofday_intf for accepted input. If input includes more than 9 decimal places in seconds, rounds to the nearest nanosecond, with the midpoint rounded up. Allows 60.sss... seconds for leap seconds but treats it as exactly 60s regardless of fractional part.

val (=) : t -> t -> bool
val (>) : t -> t -> bool
val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~cmp:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool
val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

val sign : t -> Base__.Sign0.t

Returns Neg, Zero, or Pos in a way consistent with the above functions.

val add_exn : t -> Core_kernel.Time_ns.Span.t -> t

On some days, add_exn t span doesn't occur span from t in real time. For example, this happens on days when daylight saving time begins or ends. See Time.Ofday for more detail.

val sub_exn : t -> Core_kernel.Time_ns.Span.t -> t

val now : zone:Core_kernel.Time.Zone.t -> t
val to_millisecond_string : t -> string
val start_of_day : t
val start_of_next_day : t
val approximate_end_of_day : t

The largest representable value below start_of_next_day, i.e. one nanosecond before midnight.
