Ahoy Captain NIXUDAU060 ! Please don't hold a grudge against me. Matey, have ye ever seen a Pirate wearing a wrist watch? Every Pirate day starts at first light and  ends as the Sun goes down. Pirate do not use timers. 

I have a giant hourglass on my table and that's all I could get from my last sailing. Let me explain what does my message mean: 

I'll help keep an eye on you for 2 days. But then ye're on yer own, sailor. I have better things to do than to save yer crew all the time!

It mean that today and tomorrow (20 and 21 February), I will help ye and save yer Crew from certain death. On the third day ye stay alone with ye Units and ye arrr the one who takes care of them. Matey, always hide ye Units to the Harbor or  use the Auto Crew Hider like Capt. Icy recommended. 

Piratically yers,

Anne Bonnie 

Have thanks for yerr replies, ye scurvy dogs!

Now, ordering me crew to their bunks is nerry a problem, mate Icy, once I know Anne's off the deck - it's what I've been a-doing 10 days long afore I ever got that misleadin' message.

As far as yerr explanation goes Bonnie Anne, sun's well up at 9 am by my reckoning and clocks arrr sorely required in navigatin' -- so even shallow water pyrate ought've heard of the concept.

I rrrecommend with the highest rrrespects - that ye change the wording to mean what ye think. Make it clear as rum weather it be one/two more days -- which be at least twenty-fourr hours according to the scolars, thou I hear sum Frenchmen will preferr decimal time -- or the end of the day after -- which be the beginnin' of the wee hours to all reckonin'.

That bein' said, if ye heed by yer own timin', why promise any assistance at all? It's merry and fine with me just to say ye'll stop watching eventually - if yer still around when we don't think ye arr, why would we take that against ye, lass...

If ye want me not to begrudge ye, send me back me ship's crew from where they lie at the bottom of the seas as I asked of ye! Tis not their fault the concept of the 24-hourrr day differs twixt us. With the past three days in Davy Jones' locker, they already be looking mightily bruised about now...

Fair winds fellow pyrates, 060

Ahoy Blasph, me din'na see any such clock so methinks there was none. 

Thank yee for this idea, it would be the most simple solution. 

I believe the protection clock stays even then, you are only protected through those you did not hit

yes blas is right, those under the lv30 below bubble lose protection to those they've taken any hostile action toward, which includes scouting. All other pirates can't attack you.
