$ perldoc -f sleep

sleep EXPR
        sleep   Causes the script to sleep for EXPR seconds, or forever if  
no EXPR.  May be
                interrupted if the process receives a signal such as  
"SIGALRM".  Returns the num‐
                ber of seconds actually slept.  You probably cannot mix  
"alarm" and "sleep"
                calls, because "sleep" is often implemented using "alarm".

                On some older systems, it may sleep up to a full second  
less than what you
                requested, depending on how it counts seconds.  Most modern  
systems always sleep
                the full amount.  They may appear to sleep longer than  
that, however, because
                your process might not be scheduled right away in a busy  
multitasking system.

                For delays of finer granularity than one second, you may  
use Perl’s "syscall"
                interface to access setitimer(2) if your system supports  
it, or else see "select"
                above.  The Time::HiRes module (from CPAN, and starting  
 from Perl 5.8 part of the
                standard distribution) may also help.

                See also the POSIX module’s "pause" function.
