From "Advanced Perl Programming":
$SIG{ALRM} = \&timed_out; eval { alarm(10); $buf = <>; alarm(0); }; if ($@ =~ /BLAH/) { print "Timed out."; } sub timed_out { die "BLAH" }
this will wait ten seconds for someone to enter something. the alarm(0) is to reset the timer if something does get entered (so &timed_out won't get called).

if you want high resolution timing (like 2.35), ye olde dromedary suggests using syscall to call the system timer routines (itimer).
