8.224. Time::HiRes
Provides
"high-resolution" functionality for
alarm, sleep,
gettimeofday, and interval
timers. Ordinarily, Perl deals in seconds when you use something like
sleep() or alarm(), with which
only positive integers are allowed. Time::HiRes allows you to use
more granular times for functions such as sleep()
and alarm(). For example:
#!/usr/local/bin/perl -w
use Time::HiRes qw(usleep);
my $ms = 349_000; # That's 349,000 microseconds
usleep($ms);
print "I'm awake now.\n";
Time::HiRes implements a Perl interface to
usleep(), ualarm(),
gettimeofday(), setitimer(),
and getitimer().
