The idea for this block is similar to the capacitor block, but instead of emitting redstone for a set amount of seconds, it holds back emitting it for a set amount.

You would connect it to a receiver, and when the receiver is supposed to be emitting redstone the timer will basically delay the output. It would be useful if certain aspects can override the timer.

In the GUI perhaps an option such as

Aspect override (Options, Green, Yellow, Red etc..)
As well as the capacitor GUI with the options in seconds.

If the receiver or whatever is linked to it switches aspect and one of the aspects on the override list is one of the aspects on the override list it will stop any redstone that currently being delayed that is supposed to be emitted. This I feel will make oddly shaped junctions easier to build and prevent collisions, if I've missed anything feel free to add.
