See the L</EXAMPLES> section below and the -test scripts for usage; see your system documentation for the -description of the underlying C<nanosleep> or C<usleep>, C<ualarm>, -C<gettimeofday>, and C<setitimer>/C<getitimer> calls. - -If your system lacks C<gettimeofday()> or an emulation of it you don't -get C<gettimeofday()> or the one-argument form of C<tv_interval()>. -If your system lacks all of C<nanosleep()>, C<usleep()>, -C<select()>, and C<poll>, you don't get C<Time::HiRes::usleep()>, -C<Time::HiRes::nanosleep()>, or C<Time::HiRes::sleep()>. -If your system lacks both C<ualarm()> and C<setitimer()> you don't get -C<Time::HiRes::ualarm()> or C<Time::HiRes::alarm()>. - -If you try to import an unimplemented function in the C<use> statement -it will fail at compile time. - -If your subsecond sleeping is implemented with C<nanosleep()> instead -of C<usleep()>, you can mix subsecond sleeping with signals since -C<nanosleep()> does not use signals. This, however, is not portable, -and you should first check for the truth value of -C<&Time::HiRes::d_nanosleep> to see whether you have nanosleep, and -then carefully read your C<nanosleep()> C API documentation for any -peculiarities. - -If you are using C<nanosleep> for something else than mixing sleeping -with signals, give some thought to whether Perl is the tool you should -be using for work requiring nanosecond accuracies. - -The following functions can be imported from this module. -No functions are exported by default. - -=over 4 - -=item gettimeofday () - -In array context returns a two-element array with the seconds and -microseconds since the epoch. In scalar context returns floating -seconds like C<Time::HiRes::time()> (see below). - -=item usleep ( $useconds ) - -Sleeps for the number of microseconds (millionths of a second) -specified. Returns the number of microseconds actually slept. Can -sleep for more than one second, unlike the C<usleep> system call. Can -also sleep for zero seconds, which often works like a I<thread yield>. -See also C<Time::HiRes::usleep()>, C<Time::HiRes::sleep()>, and -C<Time::HiRes::clock_nanosleep()>. - -Do not expect usleep() to be exact down to one microsecond. - -=item nanosleep ( $nanoseconds ) - -Sleeps for the number of nanoseconds (1e9ths of a second) specified. -Returns the number of nanoseconds actually slept (accurate only to -microseconds, the nearest thousand of them). Can sleep for more than -one second. Can also sleep for zero seconds, which often works like a -I<thread yield>. See also C<Time::HiRes::sleep()>, -C<Time::HiRes::usleep()>, and C<Time::HiRes::clock_nanosleep()>. - -Do not expect nanosleep() to be exact down to one nanosecond. -Getting even accuracy of one thousand nanoseconds is good. - -=item ualarm ( $useconds [, $interval_useconds ] ) - -Issues a C<ualarm> call; the C<$interval_useconds> is optional and -will be zero if unspecified, resulting in C<alarm>-like behaviour. - -Note that the interaction between alarms and sleeps is unspecified. - -=item tv_interval - -tv_interval ( $ref_to_gettimeofday [, $ref_to_later_gettimeofday] ) - -Returns the floating seconds between the two times, which should have -been returned by C<gettimeofday()>. If the second argument is omitted, -then the current time is used. - -=item time () - -Returns a floating seconds since the epoch. This function can be -imported, resulting in a nice drop-in replacement for the C<time> -provided with core Perl; see the L</EXAMPLES> below. - -B<NOTE 1>: This higher resolution timer can return values either less -or more than the core C<time()>, depending on whether your platform -rounds the higher resolution timer values up, down, or to the nearest second -to get the core C<time()>, but naturally the difference should be never -more than half a second. See also L</clock_getres>, if available -in your system. - -B<NOTE 2>: Since Sunday, September 9th, 2001 at 01:46:40 AM GMT, when -the C<time()> seconds since epoch rolled over to 1_000_000_000, the -default floating point format of Perl and the seconds since epoch have -conspired to produce an apparent bug: if you print the value of -C<Time::HiRes::time()> you seem to be getting only five decimals, not -six as promised (microseconds). Not to worry, the microseconds are -there (assuming your platform supports such granularity in the first -place). What is going on is that the default floating point format of -Perl only outputs 15 digits. In this case that means ten digits -before the decimal separator and five after. To see the microseconds -you can use either C<printf>/C<sprintf> with C<"%.6f">, or the -C<gettimeofday()> function in list context, which will give you the -seconds and microseconds as two separate values. - -=item sleep ( $floating_seconds ) - -Sleeps for the specified amount of seconds. Returns the number of -seconds actually slept (a floating point value). This function can -be imported, resulting in a nice drop-in replacement for the C<sleep> -provided with perl, see the L</EXAMPLES> below. - -Note that the interaction between alarms and sleeps is unspecified. - -=item alarm ( $floating_seconds [, $interval_floating_seconds ] ) - -The C<SIGALRM> signal is sent after the specified number of seconds. -Implemented using C<ualarm()>. The C<$interval_floating_seconds> argument -is optional and will be zero if unspecified, resulting in C<alarm()>-like -behaviour. This function can be imported, resulting in a nice drop-in -replacement for the C<alarm> provided with perl, see the L</EXAMPLES> below. - -B<NOTE 1>: With some combinations of operating systems and Perl -releases C<SIGALRM> restarts C<select()>, instead of interrupting it. -This means that an C<alarm()> followed by a C<select()> may together -take the sum of the times specified for the the C<alarm()> and the -C<select()>, not just the time of the C<alarm()>. - -Note that the interaction between alarms and sleeps is unspecified. - -=item setitimer ( $which, $floating_seconds [, $interval_floating_seconds ] ) - -Start up an interval timer: after a certain time, a signal arrives, -and more signals may keep arriving at certain intervals. To disable -an "itimer", use C<$floating_seconds> of zero. If the -C<$interval_floating_seconds> is set to zero (or unspecified), the -timer is disabled B<after> the next delivered signal. - -Use of interval timers may interfere with C<alarm()>, C<sleep()>, -and C<usleep()>. In standard-speak the "interaction is unspecified", -which means that I<anything> may happen: it may work, it may not. - -In scalar context, the remaining time in the timer is returned. - -In list context, both the remaining time and the interval are returned. - -There are usually three or four interval timers available: the -C<$which> can be C<ITIMER_REAL>, C<ITIMER_VIRTUAL>, C<ITIMER_PROF>, or -C<ITIMER_REALPROF>. Note that which ones are available depends: true -UNIX platforms usually have the first three, but (for example) Win32 -and Cygwin have only C<ITIMER_REAL>, and only Solaris seems to have -C<ITIMER_REALPROF> (which is used to profile multithreaded programs). - -C<ITIMER_REAL> results in C<alarm()>-like behaviour. Time is counted in -I<real time>; that is, wallclock time. C<SIGALRM> is delivered when -the timer expires. - -C<ITIMER_VIRTUAL> counts time in (process) I<virtual time>; that is, -only when the process is running. In multiprocessor/user/CPU systems -this may be more or less than real or wallclock time. (This time is -also known as the I<user time>.) C<SIGVTALRM> is delivered when the -timer expires. - -C<ITIMER_PROF> counts time when either the process virtual time or when -the operating system is running on behalf of the process (such as I/O). -(This time is also known as the I<system time>.) (The sum of user -time and system time is known as the I<CPU time>.) C<SIGPROF> is -delivered when the timer expires. C<SIGPROF> can interrupt system calls. - -The semantics of interval timers for multithreaded programs are -system-specific, and some systems may support additional interval -timers. See your C<setitimer()> documentation. - -=item getitimer ( $which ) - -Return the remaining time in the interval timer specified by C<$which>. - -In scalar context, the remaining time is returned. - -In list context, both the remaining time and the interval are returned. -The interval is always what you put in using C<setitimer()>. - -=item clock_gettime ( $which ) - -Return as seconds the current value of the POSIX high resolution timer -specified by C<$which>. All implementations that support POSIX high -resolution timers are supposed to support at least the C<$which> value -of C<CLOCK_REALTIME>, which is supposed to return results close to the -results of C<gettimeofday>, or the number of seconds since 00:00:00:00 -January 1, 1970 Greenwich Mean Time (GMT). Do not assume that -CLOCK_REALTIME is zero, it might be one, or something else. -Another potentially useful (but not available everywhere) value is -C<CLOCK_MONOTONIC>, which guarantees a monotonically increasing time -value (unlike time(), which can be adjusted). See your system -documentation for other possibly supported values. - -=item clock_getres ( $which ) - -Return as seconds the resolution of the POSIX high resolution timer -specified by C<$which>. All implementations that support POSIX high -resolution timers are supposed to support at least the C<$which> value -of C<CLOCK_REALTIME>, see L</clock_gettime>. - -=item clock_nanosleep ( $which, $seconds, $flags = 0) - -Sleeps for the number of seconds (1e9ths of a second) specified. -Returns the number of seconds actually slept. The $which is the -"clock id", as with clock_gettime() and clock_getres(). The flags -default to zero but C<TIMER_ABSTIME> can specified (must be exported -explicitly) which means that C<$nanoseconds> is not a time interval -(as is the default) but instead an absolute time. Can sleep for more -than one second. Can also sleep for zero seconds, which often works -like a I<thread yield>. See also C<Time::HiRes::sleep()>, -C<Time::HiRes::usleep()>, and C<Time::HiRes::nanosleep()>. - -Do not expect clock_nanosleep() to be exact down to one nanosecond. -Getting even accuracy of one thousand nanoseconds is good. - -=item clock() - -Return as seconds the I<process time> (user + system time) spent by -the process since the first call to clock() (the definition is B<not> -"since the start of the process", though if you are lucky these times -may be quite close to each other, depending on the system). What this -means is that you probably need to store the result of your first call -to clock(), and subtract that value from the following results of clock(). - -The time returned also includes the process times of the terminated -child processes for which wait() has been executed. This value is -somewhat like the second value returned by the times() of core Perl, -but not necessarily identical. Note that due to backward -compatibility limitations the returned value may wrap around at about -2147 seconds or at about 36 minutes. - -=back - -=head1 EXAMPLES - - use Time::HiRes qw(usleep ualarm gettimeofday tv_interval); - - $microseconds = 750_000; - usleep($microseconds); - - # signal alarm in 2.5s & every .1s thereafter - ualarm(2_500_000, 100_000); - - # get seconds and microseconds since the epoch - ($s, $usec) = gettimeofday(); - - # measure elapsed time - # (could also do by subtracting 2 gettimeofday return values) - $t0 = [gettimeofday]; - # do bunch of stuff here - $t1 = [gettimeofday]; - # do more stuff here - $t0_t1 = tv_interval $t0, $t1; - - $elapsed = tv_interval ($t0, [gettimeofday]); - $elapsed = tv_interval ($t0); # equivalent code - - # - # replacements for time, alarm and sleep that know about - # floating seconds - # - use Time::HiRes; - $now_fractions = Time::HiRes::time; - Time::HiRes::sleep (2.5); - Time::HiRes::alarm (10.6666666); - - use Time::HiRes qw ( time alarm sleep ); - $now_fractions = time; - sleep (2.5); - alarm (10.6666666); - - # Arm an interval timer to go off first at 10 seconds and - # after that every 2.5 seconds, in process virtual time - - use Time::HiRes qw ( setitimer ITIMER_VIRTUAL time ); - - $SIG{VTALRM} = sub { print time, "\n" }; - setitimer(ITIMER_VIRTUAL, 10, 2.5); - - use Time::HiRes qw( clock_gettime clock_getres CLOCK_REALTIME ); - # Read the POSIX high resolution timer. - my $high = clock_getres(CLOCK_REALTIME); - # But how accurate we can be, really? - my $reso = clock_getres(CLOCK_REALTIME); - - use Time::HiRes qw( clock_nanosleep TIMER_ABSTIME ); - clock_nanosleep(CLOCK_REALTIME, 1e6); - clock_nanosleep(CLOCK_REALTIME, 2e9, TIMER_ABSTIME); - - use Time::HiRes qw( clock ); - my $clock0 = clock(); - ... # Do something. - my $clock1 = clock(); - my $clockd = $clock1 - $clock0; - -=head1 C API - -In addition to the perl API described above, a C API is available for -extension writers.

They accept a date as a six-element array, and return -the corresponding time(2) value in seconds since the system epoch -(Midnight, January 1, 1970 GMT on Unix, for example). This value can -be positive or negative, though POSIX only requires support for -positive values, so dates before the system's epoch may not work on -all operating systems. - -It is worth drawing particular attention to the expected ranges for -the values provided. The value for the day of the month is the actual day -(ie 1..31), while the month is the number of months since January (0..11). -This is consistent with the values returned from localtime() and gmtime(). - -The timelocal() and timegm() functions perform range checking on the -input $sec, $min, $hour, $mday, and $mon values by default. If you'd -rather they didn't, you can explicitly import the timelocal_nocheck() -and timegm_nocheck() functions. - - use Time::Local 'timelocal_nocheck'; - - { - # The 365th day of 1999 - print scalar localtime timelocal_nocheck 0,0,0,365,0,99; - - # The twenty thousandth day since 1970 - print scalar localtime timelocal_nocheck 0,0,0,20000,0,70; - - # And even the 10,000,000th second since 1999! - print scalar localtime timelocal_nocheck 10000000,0,0,1,0,99; - } - -Your mileage may vary when trying these with minutes and hours, -and it doesn't work at all for months. - -Strictly speaking, the year should also be specified in a form consistent -with localtime(), i.e. the offset from 1900. -In order to make the interpretation of the year easier for humans, -however, who are more accustomed to seeing years as two-digit or four-digit -values, the following conventions are followed: - -=over 4 - -=item * - -Years greater than 999 are interpreted as being the actual year, -rather than the offset from 1900. Thus, 1964 would indicate the year -Martin Luther King won the Nobel prize, not the year 3864. - -=item * - -Years in the range 100..999 are interpreted as offset from 1900, -so that 112 indicates 2012. This rule also applies to years less than zero -(but see note below regarding date range). - -=item * - -Years in the range 0..99 are interpreted as shorthand for years in the -rolling "current century," defined as 50 years on either side of the current -year. Thus, today, in 1999, 0 would refer to 2000, and 45 to 2045, -but 55 would refer to 1955. Twenty years from now, 55 would instead refer -to 2055. This is messy, but matches the way people currently think about -two digit dates. Whenever possible, use an absolute four digit year instead. - -=back - -The scheme above allows interpretation of a wide range of dates, particularly -if 4-digit years are used. - -Please note, however, that the range of dates that can be actually be handled -depends on the size of an integer (time_t) on a given platform. -Currently, this is 32 bits for most systems, yielding an approximate range -from Dec 1901 to Jan 2038. - -Both timelocal() and timegm() croak if given dates outside the supported -range. - -=head2 Ambiguous Local Times (DST) - -Because of DST changes, there are many time zones where the same local -time occurs for two different GMT times on the same day. For example, -in the "Europe/Paris" time zone, the local time of 2001-10-28 02:30:00 -can represent either 2001-10-28 00:30:00 GMT, B<or> 2001-10-28 -01:30:00 GMT. - -When given an ambiguous local time, the timelocal() function should -always return the epoch for the I<earlier> of the two possible GMT -times. - -=head2 Non-Existent Local Times (DST) - -When a DST change causes a locale clock to skip one hour forward, -there will be an hour's worth of local times that don't exist. Again, -for the "Europe/Paris" time zone, the local clock jumped from -2001-03-25 01:59:59 to 2001-03-25 03:00:00. - -If the timelocal() function is given a non-existent local time, it -will simply return an epoch value for the time one hour later. - -=head2 Negative Epoch Values - -Negative epoch (time_t) values are not officially supported by the -POSIX standards, so this module's tests do not test them. On some -systems, they are known not to work. These include MacOS (pre-OSX) -and Win32. - -On systems which do support negative epoch values, this module should -be able to cope with dates before the start of the epoch, down the -minimum value of time_t for the system. - -=head1 IMPLEMENTATION - -These routines are quite efficient and yet are always guaranteed to agree -with localtime() and gmtime(). We manage this by caching the start times -of any months we've seen before. If we know the start time of the month, -we can always calculate any time within the month. The start times -are calculated using a mathematical formula. Unlike other algorithms -that do multiple calls to gmtime(). - -timelocal() is implemented using the same cache. We just assume that we're -translating a GMT time, and then fudge it when we're done for the timezone -and daylight savings arguments. Note that the timezone is evaluated for -each date because countries occasionally change their official timezones. -Assuming that localtime() corrects for these changes, this routine will -also be correct. - -=head1 BUGS - -The whole scheme for interpreting two-digit years can be considered a bug. - -=head1 SUPPORT - -Support for this module is provided via the datetime@perl.org -email list.
