POSIX::strftime behaving differently in different scripts.

[techman2006]

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.

techman2006,
The Friendly Manual for Time::Localtime:

This module's default exports override the core localtime() function, replacing it with a version that returns "Time::tm"

The reason it is not working is because you are not passing strftime() the results of the perl built-in localtime()

[Corion]

You don't show the relevant code. But as you talk of some mysterious Time::localtime - that routine is likely different from the "normal" CORE::localtime. Use the appropriate function for strftime.

[techman2006]

Actually script is quite big and later I figure out at that Time::locatime is overrides the core functions due to which error was reported.

So now I am using POSIX::locatime and other stuff to use its functionality.

Thanks.
