In SIN they can see every single time you've left and entered the country on that passport, down to the minute. Not on the first screen, though, so they need to type their way into it. I've seen one of those printouts that they ran for me for the previous 3 years - it was a few pages long

I can tell when I get a new immigration officer in NZ when they spent a few minutes paging down through the entries with a stunned look on their face.
