Dear monks, beginning Perl user here. The following code is an excerpt from a larger script taken from a book called
Baseball Hacks, published a few years ago. The author's scripts do not 'use strict' and so I tried to go through the script and make the necessary changes. One section of code which interacts with the Time::Local module has been giving me problems. Specifically, when I try to change the variable ($t) to 'my $t' or $start to 'my $start' the script runs without error except that the processing date then becomes 12/31/1969 instead of what I currently have intended which is 8/16/07. Any idea as to why this might be happening?
use Strict;
use Warnings;
use Time::Local;
# subroutine extracts and formats date from a time stamp
sub extractDate($) {
# extracts and formats date from a time stamp
($t) = @_;
my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst)
= localtime($t);
$mon += 1;
$year += 1900;
$mon = (length($mon) == 1) ? "0$mon" : $mon;
$mday = (length($mday) == 1) ? "0$mday" : $mday;
return ($mon, $mday, $year);
}
# get all data from website from 8/16/07 to present
my $start = timelocal(0,0,0,16,7,107);
($mon, $mday, $year) = extractDate($start);
print "starting at $mon/$mday/$year\n";
($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(time
+);
my $now = timelocal(0,0,0,$mday - 0,$mon,$year);
#$now = timelocal(0,0,0,$mday - 1,$mon,$year);
#$now = timelocal(0,0,0,3,10,105);
($mon, $mday, $year) = extractDate($now);
print "ending at $mon/$mday/$year\n";
for ($t = $start; $t < $now; $t += 60*60*24) {
($mon, $mday, $year) = extractDate($t);
print "processing $mon/$mday/$year\n";
