Module Ofday

Signature

include module type of Ofday with type t = Ofday.t with module Zoned := Ofday.Zoned
type t = Ofday.t

Times of day.

t represents a clock-face time of day. Usually this is equivalent to a time-offset from midnight, and each t occurs exactly once in each calendar day. However, when daylight savings time begins or ends, some clock face times (and therefore t's) can occur more than once per day or not at all, and e.g. 04:00 can occur three or five hours after midnight, so knowing your current offset from midnight is *not* in general equivalent to knowing the current t. (See Zone for tools to help you cope with DST.)

val compare : t -> t -> int
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 to_parts : t -> Span.Parts.t
val start_of_day : t

Smallest valid ofday. There is no exposed end_of_day value because the upper end of the range is not closed.

val to_span_since_start_of_day : t -> Span.t

Note that these names are only really accurate on days without DST transitions. When clocks move forward or back, of_span_since_start_of_day s will not necessarily occur s after that day's midnight.

val of_span_since_start_of_day : Span.t -> t

Due to a circular reference, this declaration is found in time.mli.

val now : zone:Zone.t -> t

val add : t -> Span.t -> t option

add t s shifts the time of day t by the span s. It returns None if the result is not in the same 24-hour day.

val sub : t -> Span.t -> t option
val diff : t -> t -> Span.t

diff t1 t2 returns the difference in time between two ofdays, as if they occurred on the same 24-hour day.

val small_diff : t -> t -> Span.t

Returns the time-span separating the two of-days, ignoring the hour information, and assuming that the of-days represent times that are within a half-hour of each other. This is useful for comparing two ofdays in unknown time-zones.

val to_string_trimmed : t -> string

trailing seconds and subseconds are trimmed off if they are 0

val to_sec_string : t -> string

trailing milliseconds are trimmed

val of_string_iso8601_extended : ?pos:int -> ?len:int -> string -> t
val to_millisec_string : t -> string

with milliseconds
