Besides what ExKage has pointed out, Garleans can't use aetherites because they are unable to use aether. That's why they abuse magitek so much, to make up for their lack of 'proper' magic. I don't think they could teleport their machinery with them, even if they could: people still use carriages, carts and ships to transport goods. This implies objects you are not currently carrying cannot be teleported via aetherite. And garleans without magitek backup are just regular mooks.
Their only choice for sending troops via aetherites would be to somehow smuggle a crapton of Ala Mhigan conscripts into, say, Ul'dah, make them attune to the aetherite and then leave...so they can teleport back again with their battle gear, I guess.
I don't see much strategical value in that: if you have troops who are already infiltrated in the city, would you make them leave so you can send them back in?
Anyway, back to the topic: I don't pay much attention to in-game time too much. I drive myself through convention: we decide if a scene is supposed to happen at a particular hour and then go with it. If it's random RP, I avoid mentioning it until someone else does. I do the same with the weather.
