=head1 DESCRIPTION
The C<Time::HiRes> module implements a Perl interface to the
resolution timers are supposed to support at least the C<$which> value
of C<CLOCK_REALTIME>, see L</clock_gettime>.
+B<NOTE>: the resolution returned may be highly optimistic. Even if
+the resolution is high (a small number), all it means is that you'll
+be able to specify the arguments to clock_gettime() and clock_nanosleep()
+with that resolution. The system might not actually be able to measure
+events at that resolution, and the various overheads and the overall system
+load are certain to affect any timings.
+
=item clock_nanosleep ( $which, $nanoseconds, $flags = 0)
Sleeps for the number of nanoseconds (1e9ths of a second) specified.
the access time stamp from t2 need not be greater-than the modify
time stamp from t1: it may be equal or I<less>.
+=item utime LIST
+
+As L<perlfunc/utime>
+but with the ability to set the access/modify file timestamps
+in subsecond resolution, if the operating system and the filesystem
+both support such timestamps. To override the standard utime():
+
+ use Time::HiRes qw(utime);
+
+Test for the value of &Time::HiRes::d_hires_utime to find out whether
+the operating system supports setting subsecond file timestamps.
+
+As with CORE::utime(), passing undef as both the atime and mtime will
+call the syscall with a NULL argument.
+
+The actual achievable subsecond resolution depends on the combination
+of the operating system and the filesystem.
+
+Returns the number of files successfully changed.

=head1 EXAMPLES
name C prototype
--------------- ----------------------
- Time::NVtime double (*)()
+ Time::NVtime NV (*)()
Time::U2time void (*)(pTHX_ UV ret[2])
Both functions return equivalent information (like C<gettimeofday>)
Here is an example of using C<NVtime> from C:
- double (*myNVtime)(); /* Returns -1 on failure. */
+ NV (*myNVtime)(); /* Returns -1 on failure. */
SV **svp = hv_fetch(PL_modglobal, "Time::NVtime", 12, 0);
if (!svp) croak("Time::HiRes is required");
if (!SvIOK(*svp)) croak("Time::NVtime isn't a function pointer");
- myNVtime = INT2PTR(double(*)(), SvIV(*svp));
- printf("The current time is: %f\n", (*myNVtime)());
+ myNVtime = INT2PTR(NV(*)(), SvIV(*svp));
+ printf("The current time is: %" NVff "\n", (*myNVtime)());
=head1 DIAGNOSTICS
Some systems have APIs but not implementations: for example QNX and Haiku
have the interval timer APIs but not the functionality.
+In pre-Sierra macOS (pre-10.12, OS X) clock_getres(), clock_gettime()
+and clock_nanosleep() are emulated using the Mach timers; as a side
+effect of being emulated the CLOCK_REALTIME and CLOCK_MONOTONIC are
+the same timer.
+
+gnukfreebsd seems to have non-functional futimens() and utimensat()
+(at least as of 10.1): therefore the hires utime() does not work.
