It would be a Math.round() expression on the time remapping, if you want to emulate posterize time.

Math.round(time) would give you a change once per second
Math.round(time*5)/5would give you a change 5 times per second
etc.

Or a similar expression on the offset, using time, but making the output 2-dimensional, for example

my_offset = 5*Math.round(time*5);
[my_offset, my_offset]


That would move 5 pixels over and down 5 times a second.

Adjust values to taste.
