.Sh DESCRIPTION
These macros are provided for manipulating the
.Fa timeval
and
.Fa timespec
structures described in
.Xr timeval 3 .
.Pp
The
.Fn timeradd
and
.Fn timespecadd
macros add the time information stored in
.Fa a
to
.Fa b ,
storing the result in
.Fa res .
With
.Fn timeradd
the results are simplified such that the value of
.Fa res->tv_usec
is always less than 1,000,000 (1 second).
With
.Fn timespecadd
the
.Fa res->tv_nsec
member of
.Fa struct timespec
is always less than 1,000,000,000.
.Pp
The
.Fn timersub
and
.Fn timespecsub
macros subtract the time information stored in
.Fa b
from
.Fa a
and store the resulting structure
in
.Fa res .
.Pp
The
.Fn timerclear
and
.Fn timespecclear
macros initialize the structures
to midnight (0 hour) January 1st, 1970 (the Epoch).
In other words, they set the members of the structure to zero.
.Pp
The
.Fn timerisset
and
.Fn timespecisset
macros return true if the input structure
is set to any time value other than the Epoch.
.Pp
The
.Fn timercmp
and
.Fn timespeccmp
macros compare
.Fa a
to
.Fa b
using the comparison operator given in
.Fa CMP .
The result of the comparison is returned.

.Sh NAME

.Nd time structures
.Sh LIBRARY
.ds str-Lb-libbsd Utility functions from BSD systems (libbsd, \-lbsd)
.Lb libbsd
.Sh SYNOPSIS

.Ft void
.Fn TIMEVAL_TO_TIMESPEC "struct timeval *tv" "struct timespec *ts"
.Ft void
.Fn TIMESPEC_TO_TIMEVAL "struct timeval *tv" "struct timespec *ts"
.Sh DESCRIPTION
The
.In sys/time.h
header, included by
.In time.h ,
defines various structures related to time and timers.
.Bl -enum -offset 1n
.It
The following structure is used by
.Xr gettimeofday 2 ,
among others:
.Bd -literal -offset indent
struct timeval {
time_t tv_sec;
suseconds_t tv_usec;
};
.Ed
.Pp
The
.Va tv_sec
member represents the elapsed time, in whole seconds.
The
.Va tv_usec
member captures rest of the elapsed time,
represented as the number of microseconds.
.It
The following structure is used by
.Xr nanosleep 2 ,
among others:
.Bd -literal -offset indent
struct timespec {
time_t tv_sec;
long tv_nsec;
};
.Ed
.Pp
The
.Va tv_sec
member is again the elapsed time in whole seconds.
The
.Va tv_nsec
member represents the rest of the elapsed time in nanoseconds.
.Pp
A microsecond is equal to one millionth of a second,
1000 nanoseconds, or 1/1000 milliseconds.
To ease the conversions, the macros
.Fn TIMEVAL_TO_TIMESPEC
and
.Fn TIMESPEC_TO_TIMEVAL
can be used to convert between
.Em struct timeval
and
.Em struct timespec .
.El
.Sh EXAMPLES
It can be stressed that the traditional
.Tn UNIX
.Va timeval
and
.Va timespec
structures represent elapsed time, measured by the system clock.
The following sketch implements a function suitable
for use in a context where the
.Va timespec
structure is required for a conditional timeout:
.Bd -literal -offset indent
static void
example(struct timespec *spec, time_t minutes)
{
struct timeval elapsed;
(void)gettimeofday(&elapsed, NULL);
_DIAGASSERT(spec != NULL);
TIMEVAL_TO_TIMESPEC(&elapsed, spec);
/* Add the offset for timeout in minutes. */
spec->tv_sec = spec->tv_sec + minutes * 60;
}
.Ed
.Pp
A better alternative would use the more precise
.Xr clock_gettime 2 .
