It appears to be the maximum delay that you can add to input and output.

I've only found documentation[1] for it on Stratix III, but I guess it's similar on MAX 10.

According to the MAX 10 datasheet[2], minimum offset is always zero, and the maximum offset is small in the fast corner, and large in the slow corner. If you need fast I/O, it should not matter which pins you use.
