does the outer end of a second hand on a clock move faster than the inner end seeing as it has a much greater distance to travel in the same time?

er... yes. You have already answered your question.
However, all parts of the second hand move round the clock face at the same ANGULAR velocity, assuming it is rigid....... but a clock with bendy hands would be of limited use.
Now there's a starting point for some weird stuff.....
Just a second, I'll go see . . .
Yep it does!
Now there both right back where they started . . .

Well they were.
But it all goes at 1 rpm
Sorry to hijack your post, but just wondering....
Theoretically, if you spin a long rope to just below the speed of light, will the end of the rope be moving faster than the speed of light, as it will have to travel faster to cover the greater distance?
If the inner end of any second hand travels in a wee circle of 5mm then it's going 5mm per second. If the outer end has to make a bigger circle of 15mm, it obviously has to go faster to cover a greater distance in teh same time.

Obviously both are the same R(otation)PM but that ignores the speed to cover the rotation.
