Translation:We always had lunch exactly at one o'clock.
If it's like the cognates of those words in English, "accurate" means scientifically correct (an accurate watch tells the correct time, though you may only be able to tell what the hour is) while "precise" means with very little variance (a precise watch may tell the wrong time, but whatever time it tells is specified down to the millisecond.)
The actual word I was thinking of was aktuale.
Ah... that explains why I couldn't reconcile what I wrote here with what I wrote in the other thread (about a different word!). I must be tired. I'm glad one of us figured it out. I'm headed into work shortly. I guess this means it's going to be a long night.
(Hmmm - I thought I'd replied once more with a link to the phrase. I hope the comment was deleted or failed to post, because if I posted it in the WRONG thread, I'm going to be REALLY confused when I find it in six months. Big Grin.)
