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

module Ofday : Core__.Time_ns_intf.Ofday

See Time.Ofday.

String conversions use the local timezone by default. Sexp conversions use get_sexp_zone () by default, which can be overridden by calling set_sexp_zone. These default time zones are used when writing a time, and when reading a time with no explicit zone or UTC offset.

Sexps and strings display the date, ofday, and UTC offset of t relative to the appropriate time zone.

val bin_read_t : t Bin_prot.Read.reader
val __bin_read_t__ : (int -> t) Bin_prot.Read.reader

This function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.

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 ~compare: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

between t ~low ~high means low <= t <= high

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 get_sexp_zone : unit -> Zone.t
val set_sexp_zone : Zone.t -> unit
val t_of_sexp_abs : Core__.Import.Sexp.t -> t

t_of_sexp_abs sexp as t_of_sexp, but demands that sexp indicate the timezone the time is expressed in.

val sexp_of_t_abs : t -> zone:Zone.t -> Core__.Import.Sexp.t
val of_date_ofday_zoned : Core__.Import.Date.t -> Ofday.Zoned.t -> t

Conversion functions that involved Ofday.Zoned.t, exactly analogous to the conversion functions that involve Ofday.t

val to_date_ofday_zoned : t -> zone:Core__.Import_time.Time.Zone.t -> Core__.Import.Date.t * Ofday.Zoned.t
val to_ofday_zoned : t -> zone:Core__.Import_time.Time.Zone.t -> Ofday.Zoned.t
val to_string_fix_proto : [ `Utc | `Local ] -> t -> string
val of_string_fix_proto : [ `Utc | `Local ] -> string -> t
val of_string_abs : string -> t

This is like of_string except that if the string doesn't specify the zone then it raises rather than assume the local timezone.

val of_string_gen : if_no_timezone:[ `Fail | `Local | `Use_this_one of Zone.t ] -> string -> t

of_string_gen ~if_no_timezone s attempts to parse s to a t. If s doesn't supply a time zone if_no_timezone is consulted.

val pause : Span.t -> unit

pause span sleeps for span time.

val interruptible_pause : Span.t -> [ `Ok | `Remaining of Span.t ]

interruptible_pause span sleeps for span time unless interrupted (e.g. by delivery of a signal), in which case the remaining unslept portion of time is returned.

val pause_forever : unit -> Core__.Import.never_returns

pause_forever sleeps indefinitely.
