Module Posix_time2.Timeval

POSIX timeval: time with microsecond precision.

type t = private {
  1. tv_sec : int64;
  2. tv_usec : int64;
}

Time value with seconds and microseconds. A normalized value has tv_usec between 0 and 999999 (inclusive).

val create : int64 -> int64 -> t

create sec usec creates a new normalized timeval.

val add : t -> t -> t

add t1 t2 adds two timeval values, returning a normalized result.

val sub : t -> t -> t

sub t1 t2 subtracts t2 from t1, returning a normalized result.

val add_sec : int64 -> t -> t

add_sec s t adds s seconds to t.

val add_usec : int64 -> t -> t

add_usec us t adds us microseconds to t.

val sub_sec : int64 -> t -> t

sub_sec s t subtracts s seconds from t.

val sub_usec : int64 -> t -> t

sub_usec us t subtracts us microseconds from t.

val to_string : t -> string

to_string t returns a string in the form "sec.usec".

val compare : t -> t -> int

compare t1 t2 compares two time values. Returns 0 if equal, negative if t1 < t2, positive if t1 > t2.
