Right now I do not have Date::Calc installed and I'm trying to figure out how I can get the value in days of two dates. Here is my code to give you an idea of what I'm trying to accomplish.

If I somehow can get date::calc installed could I just then do $diff_in_days = Delta_days($sysdate, $installed_date)? Also in the event I can't install date::Calc can you please give a suggestion of how else to accomplish this?

use POSIX qw(strftime);
use Time::Local;
#use Date::Calc qw(:all);
#use time::Piece;
#use Date::Calc qw(Delta_Days);

sub give_warning
{
  my($carrier) = @_;
  my($installed_date);
  my($max_days) = 15;
  $installed_date = get_value($carrier ."_DAYS", $trn_info, '') ;
  printf("Value of Carrier Days is $installed_date \n");
     if ($installed_date ne "" )

     {          
        my $sysdate = decode_date ('SYSDATE','CCYYMMDD');
        printf("Todays date is $sysdate \n");

       my $diff_in_days = $sysdate - $installed_date ;

       print "Difference in days: $diff_in_days\n";

       if $result > $max_days
         # give error and return
       {
         &print_error ("New Installation is required.");
         return 1;
        } 
       elsif $result  <= $max_days
         # give warning and return
      {
       &print_warning ("New Installation is required.");
       return 0;
       }
     }
     else 
     {
     return 0;
     }
}
