Wow, I didn't know about File::ReadBackwards! I'll have to try that. Here's what I've been doing to parse an Apache error log at work that's never been rotated. I use a start date and an end date, but I think the same principle should apply to times. 
use Tie::File;

tie my @lines, 'Tie::File', 'error.log';

LINE:
    for (my $i=$#lines; $i >= 0; $i--) {

    my $d = substr($lines[$i], 1, 24);
    my $file_date = $time{"yyyy-mm-dd", ParseDate($d)};
    
    next LINE if ($file_date gt $edate);
    last LINE if ($file_date lt $sdate);
        # process here
}
