The FAQ partially addresses your question...
In here,, look under the question about effiency modes. Number 15 is Timer Bars, which controls, among other things, Chronometer, Antagonist, and oCD. You are able to turn those mods off or on completely during various situations in the Efficiency Settings menu, inside the main Mazzle menu.
To turn them off individually or configure them, you'll have to dig a bit deeper in the Mazzle menu, under where the individual mods are located. I *think* there's a section specifically for Timer Bars, but I might be wrong. (I need to stop answering questions away from my WoW computer.)
So, to answer your questions about what they're called, they're Chronometer, Antagonist, and oCD. Chronometer I believe controls the ones that show up in the middle of the screen, so that should be the one you should look to configuring first.
Dang, you reminded me, I need to check those and see if I can get them to show the tooltips for the bars that they're showing, I like bieng able to read the sepcific effects of a debuff being cast on me.
