$time = localtime(time);
($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst)=localtime(time);

$newtime = printf ("%4d-%02d-%02d %02d:%02d:%02d",$year+1900,$mon+1,$mday,$hour,$min,$sec);

print "$newtime\n";


Any suggestions?

Thanks in advance.
You can't, you need to to use sprintf.

Time::localtime(3pm)					 Perl Programmers Reference Guide				      Time::localtime(3pm)

NAME
Time::localtime - by-name interface to Perl's built-in localtime() function SYNOPSIS
use Time::localtime; printf "Year is %d ", localtime->year() + 1900; $now = ctime(); use Time::localtime; use File::stat; $date_string = ctime(stat($file)->mtime); DESCRIPTION
This module's default exports override the core localtime() function, replacing it with a version that returns "Time::tm" objects. This object has methods that return the similarly named structure field name from the C's tm structure from time.h; namely sec, min, hour, mday, mon, year, wday, yday, and isdst. You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. (Note that this still overrides your core functions.) Access these fields as variables named with a preceding "tm_" in front their method names. Thus, "$tm_obj->mday()" corresponds to $tm_mday if you import the fields. The ctime() function provides a way of getting at the scalar sense of the original CORE::localtime() function. To access this functionality without the core overrides, pass the "use" an empty import list, and then access function functions with their full qualified names. On the other hand, the built-ins are still available via the "CORE::" pseudo-package. NOTE
While this class is currently implemented using the Class::Struct module to build a struct-like class, you shouldn't rely upon this. AUTHOR
