My time zone is KST(South Korea republic), but when I executed following command in my system(openbsd),I got GMT time.

Which command do you mean? If you mean Perl's output, gmtime will give you GMT, and localtime will give you whatever the current time zone setting on that machine is. If you want more advanced functionality than that, then you need to switch to DateTime.

And thanks for your concern for using old version, but I can't not upgrade. It is not my authority.

Similar advice as in Yes, even you can use CPAN applies.
