How do GC achievements work exactly?

Let's say I'm playing a game offline, and I earn an achievement such as kill 200 enemies, would they sync once I finally attempt to get online? Does it matter if I'm signed into Game Center offline?

Reading some reports, quite a few seem to have a problem with Game Center so I just wanted to be sure.

They should sync when you get back online, but it's (at least for me) different with each game. Some are synced automatically, some only sync when I launch the game again and some only sync after I get a new achievement while online.

Errors are common for me though, I got 2 achievements in Pocket planes today while I was offline and only one of them was synced when I connected to Wi-Fi.
