Cook rhubarb, onion, and brown sugar in a 3- to 4-quart heavy saucepan over moderate heat, stirring, until sugar is dissolved into juices released by rhubarb and onion. Continue to cook, stirring occasionally, until rhubarb is tender and begins to break down, 15 to 20 minutes.

Add dates, raisins, mustard, spices, salt, and vinegar and simmer, stirring occasionally, until mixture is thickened, 15 to 20 minutes. Transfer to a shallow bowl and cool to room temperature, stirring occasionally, about 1 hour.
