I don't know why, but I've been searching for Ralts and have had rotten luck. I was playing earlier and finding them quite easily, but for the past two hours I haven't found a single one. Is there some kind of invisible night mode in Emerald? (Which would explain the pointless clock setting). I'm really hesitant to chalk this up to luck because I found like 3 early on and can't find a SINGLE ONE AFTER THAT.
