A timeout question using Net::FTP

I have a script to download files. It checks the remote and local directories, and downloads any new files from the remote location.

Here is part of my code:
my $ftp = Net::FTP->new
(
"ftp.xxx.yy",
Timeout => 3600,
Debug => 0
) or die "Could not connect: $@\n";

My question is, what units are the Timeout option in? The docs don't make it clear, and I'm guessing the units are seconds. Anyone have a definitive answer?
