Can someone tell me what all this stuff means please:


07:55:42 A(Fleet) From the planet [ X: X: X] reaches the planet [Y: Y: Y]. It's mission Destroy

17:29:07 A (Fleet) from the planet [Y: Y: Y] back on the planet [X: X: X]. Its mission: Destroy

08:53:06 A(Fleet) From the planet [ Y: Y: Y] reaches the planet [Z: Z: Z]. It's mission Destroy

19:34:12 A (Fleet) from the planet [Z: Z: Z] back on the planet [Y: Y: Y]. Its mission: Destroy

I phalanxed planet [Y:Y:Y]. Are the numbers times or time until it lands? What is a destroy mission? All 3 of these planets are owned by the same person. Please tell me anything else that may be helpful too. Thanks.

i think it is the person has fleetsaved just before he sets off to work
fleetsaved used is destroy moon (maybe he dont like his moons )

ACS Defend shows up as Destroy
