The Time::HiRes module implements a Perl interface to the usleep, nanosleep, ualarm, gettimeofday, and setitimer/getitimer system calls, in other words, high resolution time and timers. See the \"EXAMPLES\" section below and the test scripts for usage; see your system documentation for the description of the underlying nanosleep or usleep, ualarm, gettimeofday, and setitimer/getitimer calls.
