As debugging 101, I ran the first part of your code (below). Making a simple example for us is good, but in the future please make it a "runnable as is" example.

An obvious problem is that colon ":" is not valid in a Windows file name. Also regardless of that issue, the complete path does look a bit suspicious to me - that path does not exist on the Windows machine I'm writing this post upon using to write this post. 

#!/usr/bin/perl
use strict;
use warnings;
use POSIX qw(strftime);

my $creationTime = strftime "%F-%R:%S", localtime;

my $sqlLog = "C:/Users/thclotworthy/squirrel/logs/squirrel-sql-" . $cr
+eationTime . ".log";

my $scriptLog = "C:/Users/thclotworthy/squirrel/logs/squirrel-" . $cre
+ationTime . ".log";

print "$sqlLog\n$scriptLog\n";

__END__
prints:
C:/Users/thclotworthy/squirrel/logs/squirrel-sql--:23.log
C:/Users/thclotworthy/squirrel/logs/squirrel--:23.log

As an extra updated note: I use Windows as my development platform and often move programs to a Unix environment. I try to only use file names that are compatible with both Windows and Unix. For example Windows allows a "space" in the name but Unix does not.(see post by choroba - my recollection of this is was evidently wrong). So I use underscore "_" instead of that (where possible). Of course there are situations on Windows where a space is need, e.g. "My Documents". Always use "/" instead of "\" for path names. That even works from the Windows command line (which BTW is NOT DOS). There are some weird situations where the backslash is needed, but I encounter this so rarely that I can't think of such an example right now. Perl is amazingly good at being multi-platform.
