hi dwm, i edited your code to the below and when i ran it with root profile, still reply the header alone and without much info :( 

#!/usr/local/bin/perl -w
use strict;
use warnings;
use Time::Local;
my $debug = shift || 0;
my $header = 0;
my $infile = 'tollog-2007-jan-01.txt';
my $outfile = 'report-2007-01-01.txt';
my($fh_out, $fh);
open($fh, '<', $infile) or die "Could not open logfile: $!";
open($fh_out, '>', $outfile) or die "Could not open outfile: $!";
my %track;
while (<$fh>){
  my ($date,$ignoreIDLiteral,$id) = split / - | id = /;
  if ( $debug ) {
      print "Date = $date\n";
      print "Literal = $ignoreIDLiteral\n";
      print "ID = $id\n";
  }
  chomp $id;
  my   $time = dateconv($date);
  my $prevtime = $track{$id}{TIME};
  $track{$id}{TIME}=$time;
  $track{$id}{DATE}=$date;
  $track{$id}{COUNT}++;
  if ( $prevtime and ( $time - $prevtime > 3600 ) ) {
      unless ( $header ) {
          print "TIDS               TIME                    OCCURANCE\
+n";
          print "====================================================\
+n";
          $header = 1;
      }
      print "$id\t$date\t$track{$id}{COUNT}\n"
  }

}
sub dateconv{
  my $d = shift;
  my %month = qw[jan 1 feb 2 mar 3 apr 4 may 5 jun 6 jul 7
                 aug 8 sep 9 oct 10 nov 11 dec 12];
  my @p = $d=~/(\d+)-(\w+)-(\d+)\s(\d+):(\d+):(\d+)/;
  $p[1]=$month{ lc $p[1]  } - 1;
  return  timelocal(@p[5,4,3,2,1,0]);
}
close $fh_out;

by the way, what does $ignoreIDLiteral to mean over here ? does the ID refers to the ID field in the source data ?
