Hi! Could you add Alter Time spell to Bigdebuffs, and track like Temporal Shield? Would be a great help.

Go into

C:\Program Files (x86)\World of Warcraft_retail_\Interface\AddOns\BigDebuffs\Retail

and add

[110909] = { type = BUFF_OTHER }, -- Alter Time

all the way at the bottom, with the "other buffs"
