Hi all, I have an old perl code running from perl 5 version 12 using DateManip and DateCalc on Solaris which runs as it should. We have recently migrated to linux perl 5 version 16 and the DateCalc function doesn't work at all. I am trying to count days between two dates for example, i have tried to output what are the inputs to the DateCalc function

use Date::Manip;
my $dt1='2016080100:00:00';
my $dt2='2016123100:00:00';
my $dtopt= DateCalc($dt1,$dt2);
print $dtopt;

The above code outputs 0:0:0:0:6576:0:0 where as the old version on Solaris outputs as +0:0:+21:5:1:0:0 I am expecting the output to be as old version of perl. I know there is some problem with the format but unable to figure it out. I would really appreciate any help. I have tried to use ParseDate,Delta_Format but the result is same. P.S this is not my code i am trying to fix this. Many Thanks, Teju
