Does anyone know if Mithirl Stopwatch, Sundial of the Exalted, and Abysaal Rune Stack?

Title pretty much says it all duals procs would = +1180 spell power.

Anyone know if any of those stiack?

Wowhead comments said that Mithril Stopwatch and Abysal Rune do stack. But Mithril Stopwatch and Sundial do not stack.

I am a little worried it the current stacking was just an oversight and it will get fixed to not stack.

It looks like the Brewfest trinkets are exact replicas of the 40 emblems of heroism trinkets, and do not stack with them.

Since that is the case, and Sundial and Abyssal rune always stacked, I would think the Brewfest one should stack with Abyssal rune.

The Mithril Trinket stacks with Sundial.

Abysal Rune and Sundial have always stacked.

Since ToC came out I have used Abysal Rune and the Sundial as my trinkets. The twin procs are pretty good.
