As I recall it was something like 30s to activate overt and 5mins to go back to covert.
I have been trying to think of a way to put my 'case' forward for this.
What I can think of at the moment is it would/could make PvP more spontanious. One faction can roll up to a place under cover so to speak, and declare via /pvp "over the radio", and start things off.
I know the TEF system will pop you overt for a period of time, but if say two opposite faction members are at a starport (or the middle of Tat/Naboo/insert planet here and they want to fight, but there is no recruiter and neither are at that time overt and they cannot therefore TEF, only /PvP would work.
On a side note, but not unrelated, I still do not see how padawans at a certain skillpoint investment would be permaovert. If jedi are in hiding it would not make sense (and just because it happened in pre cu does not make it right, that's why Ed and the devs call this pre-cu+ (making it better than pre cu).
The robes worn are the standard garb of Tatooine or Jakku - simple utilitarian garments. Lightsabres would be hidden or hanging from a belt (game mechanics prevent this) and if a dark or light jedi had to use the sabre, they would (and maybe use the /PvP command then, like other profs, slink back into the shadows after with a five min timer.
They would of course be on the terms as they were combatting a player or NPC.
(I suppose they could leave with a parting shot of /jediMindTrick that I mentioned in another post
