=head1 DESCRIPTION
The B<s_time> command implements a generic SSL/TLS client which connects to a
remote host using SSL/TLS. It can request a page from the server and includes
the time to transfer the payload data in its timing measurements. It measures
the number of connections within a given timeframe, the amount of data
transferred (if any), and calculates the average time spent for one connection.
