I am trying to use POSIX::strftime to get the timezone of the system. Below is the script which perform this job.

#!/usr/bin/perl
#
use strict;
use warnings;
use POSIX qw(strftime);

my $timeZone = strftime "%z", localtime();

print "$timeZone \n";

Output:
# perl t3.pl
+0100

Now when I merge this logic in another script it an getting below error.

Usage: POSIX::strftime(fmt, sec, min, hour, mday, mon, year, wday = -1
+, yday =
        -1, isdst = -1) at test.pl line 2537 (#1)
    (F) You called a POSIX function with incorrect arguments.
    See POSIX/FUNCTIONS for more information.

Uncaught exception from user code:
        Usage: POSIX::strftime(fmt, sec, min, hour, mday, mon, year, w
+day = -1, yday = -1, isdst = -1) at test.pl line xxxx.

I am not able to get why this error is coming. Here one thing to be noted that I am using Time::localtime for some purpose.

So even I tried to use specific function from the package but still I am getting same error.

Any thoughts why this error could be coming.
