help with perl while loop
Can anyone tell me why this program won't kick out when the time gets beyond time in the loop?
sub showtime
{
local($format,$military)=@_;
($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst)=localtime(time);
if ((! $military) && ($hour > 12)) {$hour-=12;}
$min=sprintf("%02d",$min);
$sec=sprintf("%02d",$sec);
$format =~ s/SS/$sec/g;
$format =~ s/HH/$hour/g;
$format =~ s/MM/$min/g;
return $format;
}
printf &showtime("The Time is Now HHMM\n",1);
while ($showtime le 2345)
{
while ($x==0 )
{
if (-e $legrun)
{
$x=0;
sleep 10;
}
else
{
$x=1;
}
}
$x=0;

I am using a Perl script to open a series of files in a loop, separate the paragraph into lines, and output the lines into a new file. The code works perfectly fine, except when the source file is over a certain size the loop gets stuck and won’t move on to the next file. It still does what it is... (0 Replies)

time::localtime5.16
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.
