I assume you're talking about the timeout of the imap connection and not the SOAP connection?  I haven't tried it, but it looks like you could just add: 
Timeout => 20,
to your imap connection setup, somewhere around line 255.  So it would look like this:
##
## OPEN AN IMAP SESSION
##
  my $imap = Mail::IMAPClient->new(
                                   Server   => $imapHost,
                                   User     => $imapUser,
                                   Password => $imapPass,
                                   Timeout => 20, # number of seconds
                                   UID      => 1,
                                   Clear    => 1, # no buffering
                                  )
    or die "imap2soap: Cannot connect to $imapHost as $imapUser: $@ \n";
