Your input data's probably not as described. Please post a sample of it.
I am actually ok with the first piece of code that uses the fixed size split. I can delete the first 'broken' row from each file. The effect will be minimal for what I need to do.
If y'say so. Your file names will have nothing to do with their contents unless by sheer coincidence.

No wonder, my script was expecting the date at the beginning of the line.

use Time::Local;
use POSIX qw(mktime strftime);

my $start=0, $end=0, $FMT="%Y%m%d.%H%M";

        # Split each line apart into the default $_ / @_ variable
        # Last token is date.  Split apart date and time into two vars.
        ($mdy, $hms)=split(" ", @_[$#_]);
        #Split apart MM/DD/YYYY on /
        ($m, $d, $y)=split("/", $mdy);
        # Split apart HH:MM:SS on :
        ($hour, $min, $sec)=split(":", $hms);

        # Create a timestamp in epoch seconds from it.  $m-1 because Perl counts months 0-11
        $ldate=timelocal($sec, $min, $hour, $d, $m-1,$y);
        $min=$min-($min%15);    # chunks of 15 minutes

        # Check which date range it's in and change the output file as appropriate
        if($ldate >= $end)
                $end=$start + (15*60);
                        strftime("$FMT", localtime($start)),
                        strftime("$FMT", localtime($end)));

                FILE && close(FILE);
                open(FILE, ">$fname");

        print FILE "$line";

FILE && close(FILE);
exit 0;
