of_string supports and correctly interprets 12h strings with the following suffixes:

      "A", "AM", "A.M.", "A.M"
      "P", "PM", "P.M.", "P.M"

as well as the lowercase and space-prefixed versions of these suffixes.

of_string also fully supports 24h wall-clock times.

to_string only produces the 24h format.

val start_of_day : t

Smallest valid ofday.

val start_of_next_day : t

Largest representable ofday; see notes above on how start_of_next_day behaves differently from other ofday values.

val approximate_end_of_day : t

A time very close to the end of a day. Not necessarily the largest representable value before start_of_next_day, but as close as possible such that using this ofday with Time.of_date_ofday and Time.to_date should round-trip to the same date. With floating-point representations of time, this may not be possible for dates extremely far from epoch.

The clock-face time represented by approximate_end_of_day may vary with different time and ofday representations, depending on their precision.

val to_span_since_start_of_day : t -> Core_kernel.Time.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_exn s will not necessarily occur s after that day's midnight.

val of_span_since_start_of_day_exn : Core_kernel.Time.Span.t -> t
val of_span_since_start_of_day : Core_kernel.Time.Span.t -> t
  • deprecated [since 2018-04] use [of_span_since_start_of_day_exn] instead
val add : t -> Core_kernel.Time.Span.t -> t Base.Option.t

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 -> Core_kernel.Time.Span.t -> t Base.Option.t
val next : t -> t Base.Option.t

next t return the next t (next t > t) or None if t = end of day.

val prev : t -> t Base.Option.t

prev t return the previous t (prev t < t) or None if t = start of day.

val diff : t -> t -> Core_kernel.Time.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 -> Core_kernel.Time.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 -> Base.String.t

Trailing groups of zeroes are trimmed such that the output is printed in terms of the smallest non-zero units among nanoseconds, microseconds, milliseconds, or seconds; or minutes if all of the above are zero.

val to_sec_string : t -> Base.String.t

HH:MM:SS, without any subsecond components. Seconds appear even if they are zero.

val of_string_iso8601_extended : ?pos:Base.Int.t -> ?len:Base.Int.t -> Base.String.t -> t

24-hour times according to the ISO 8601 standard. This function can raise.

val to_millisecond_string : t -> Base.String.t

with milliseconds

val to_millisec_string : t -> Base.String.t
  • deprecated [since 2018-04] use [to_millisecond_string] instead
