Returns the time of the passed server in seconds since the epoch.
A connection to TCP port 37 of the server is opened, and the time
is read.
If an error happens, or the timeout occurs, the exception
<code class="code">Time_not_available</code> is raised.
The timeout is 5 seconds by default but can be set using the
<code class="code">timeout</code> parameter.
<p>
TCP has been chosen for security reasons, for example, there may be
a firewall between this system and the remote host. It is much simpler
to get a TCP port opened than a UDP port.<br>
