I didn't set it to 24 I tried 0 and 00, thats why the error seems odd to me. here is the beginning of the sub where this is located

sub minutes_before
{
    my $minutes_b4=shift;
    my $month=shift;
    my $day=shift;
    my $hour=shift;
    my $minute=shift;

    my $MONTHNUM=&month_to_num($month);

    ( $day < 10 ) ? $FDAY="0$day" : $FDAY=$day;

    # Lets find n minutes before!
    $datetime=DateTime->new( year   => 2005,
                             month  => $MONTHNUM,
                             day    => $FDAY,
                             hour   => $hour,
                             minute => $minute,
                             second => 00 );
my $formatter=DateTime::Format::Epoch->new(
                      epoch              => $datetime,
                      unit               => 'seconds',
                      type               => 'int', # or 'float', or 'b
+igint'
                      skip_leap_seconds  => 1,
                      start_at           => 0,
                      local_epoch        => undef );

    my $seconds=$formatter->format_datetime($datetime);

    my $conv_seconds=$minutes_b4 * 60;
    $seconds=$seconds-$conv_seconds;

    # And we are left with n seconds before our search time
    my $MinBefore=$formatter->parse_datetime( $seconds );

    # Now we'll reformat $MinBefore to fit the log file
    my ($DATE2, $TIME2)=split(/T/, $MinBefore);
    ($YEAR2, $MONTH2, $DAY2)=split(/-/, $DATE2);

    $MONTHNAME2=&num_to_month($MONTH2);

    ($HOUR2, $MINUTE2, $SECOND2)=split(/:/, $TIME2);
    # End of reformatting $MinBefore

    $DAY2=~s/^0+//;
    $ready=1;
    return @MINBEFORE=($MONTHNAME2, $DAY2, $HOUR2, $MINUTE2);
}

and here is where $hour gets set:

if ( defined (param('MONTH')) and
     defined (param('DAY'))   and
     defined (param('HOUR'))  and
     defined (param('MINUTE')) )
{
    $MONTH=param('MONTH');
    $DAY=param('DAY');
    $HOUR=param('HOUR');
    $MINUTE=param('MINUTE');

snip...

@M1=&minutes_before(1, $MONTH, $DAY, $HOUR, $MINUTE);

The code works as its supposed to execept when I enter 0 or 00.
Thanks

update
$hour % 24 didn't work either.
