How to random offset with materials?

My goal is to effectively make a glitch appearance without using post processing. I want this effect applied only to a material.

The way I thought about doing this is to add an ever changing offset to the UV tiling of the material source texture (Paper2D sprite in this case).

I’m finding it difficult to generate a random value and adjusting it’s frequency.

EG: Material will flicker between 0.7 and 1.3 UTiling every half a second or so.

I was hoping someone could point me in the right direction.

You could add a flipbook node to a generic noise texture, or use the Noise function with Time as an input.
