dda has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,

I'm getting the following message in webserver's error_log:

Prototype mismatch: sub main::localtime (;$) vs none at /home/httpd/ht
+ml/ds/vn.pl line 12

[download]
Lines 11 and 12 of my script are: 
use Time::localtime;
use POSIX qw (locale_h localtime);

[download]
I need to use both modules. Is it possible to get rid of this (warning?) message?

Re: Prototype mismatch when using two modules with the same function

    First guess: use one of the functions with the fully qualified name: 

    use Time::localtime;
use POSIX qw(locale_h);
[...]
POSIX::localtime();
localtime() # package Time::localtime

    should work, if I'm not completly mistaken.

      It works. Thanks!

      Most funny thing is that I used POSIX::localtime with the fully qualified name already. So I just removed 'localtime' from 'use POSIX' statement. :)

    perldoc Time::localtime 
    DESCRIPTION
This module's default exports override the core localtime() function ...
    perldoc POSIX 
    localtime
        This is identical to Perl's builtin "localtime()" function for
        converting seconds since the epoch to a date see "localtime" in
        perlfunc.
    This is mostly true. The difference is that POSIX::localtime demands you pass it an argument, while CORE::localtime does not (it assumes the value of time): 
    C:\>perl -e"die ~~localtime"
Sat Jun 21 05:23:53 2003 at -e line 1.

C:\>perl -MPOSIX=localtime -e"die ~~localtime"
Usage: POSIX::localtime(time) at -e line 1

    you can also call directly localtime() from each module
    for example POSIX::localtime() and Time::localtime()
