(perl version 5.8.7)

I have two date strings and and try to calculate date and time difference between two dates and times.

But the difference looks incorrect, could you help me to get the correct value?

notBefore=Nov 23 22:31:12 2019 GMT

notAfter=Mar 19 06:52:23 2020 GMT

#!/usr/bin/perl
use Time::Local;

# FILE READ IN
$log_file = './raw.txt';
open(FH, '<',  $log_file) or die $!;

while (<FH>) {
 if(m/START/) {chomp; $sdname = $_;}
 if(m/notBefore/) {
   chomp; ($notB1, $notB2) = split('=', $_);
   $notB2 =~ tr/:/ /;
   my($mon,$mday,$hour,$minute,$sec,$year)=split(/ /,$notB2);
   #print $mon, $mday, $hour, $minute, $sec, $year;
   $time_1 = timelocal($sec,$minute,$hour,$mday,$mon,$year);
 }
 if(m/notAfter/) {
   chomp; ($notA1, $notA2) = split('=', $_);
   $notA2 =~ tr/:/ /;
   my($mon,$mday,$hour,$minute,$sec,$year)=split(/ /,$notA2);
   $time_2 = timelocal($sec,$minute,$hour,$mday,$mon,$year);
 }
 if(m/END/) {printf("%s %s %s\n", $sdname, $notB2, $notA2);
   print $time_2,"\n",$time_1, "\n";
   $diff_time = $time_2 - $time_1;
   $diff_time1 = ($diff_time/86400);
   print "diff_time :$diff_time:$diff_time1:\n";
 }
}
