As someone else pointed out (and a bit of research confirms) it is not
 likely that the GPS on the bridge provides time in any usable form[1].

While the ship's officers are probably very protective of the equipment
on their bridge and hostile to the idea of mounting antennas and
drilling holes anywhere on the ship, they may be barely aware of the
existence of the LAN and couldn't care less what the geeks do with it
(as long as they drill no holes).  After all, it does nothing important
(i.e., steer the ship or control the engines).

[1]  A bit of Googling indicates that the major players are trying to
lock ships into proprietary networks for bridge electronics.
