will
+                                        start an interactive shell.  The shell
+                                        that is used will be determined by the
+                                        SSH server, normally by reading the 
user's
+                                        default login shell specified in
+                                        <filename>/etc/passwd</filename>.  If 
you

specific

+                                        server allows arbitrary commands to be
+                                        run, the session will attempt to start

not specified, the SSH

+                                        connections is by setting the
+                                        <envar>TZ</envar> variable on the SSH
+                                        connection to the timezone specified by
+                                        this parameter.  This means that the 
SSH
+                                        server must allow the <envar>TZ</envar>
+                                        variable to be set/overriden - many SSH
+                                        server implementations have this 
disabled
+                                        by default.  To get this to work, you 
may
+                                        need to modify the configuration of the
+                                        SSH server and explicitly allow for
+                                        <envar>TZ</envar> to be set/overriden.

+                                        The available values of this parameter 
are

timezones,
+                                        and the value will be sent directly to
+                                        the server in this format.
