Looks like @coolstarorg has done it again last night he uploaded a new staple tweak to the BigBoss repo called ClassicClock.
What this tweak does is just what ClassicDock does. It gives themers back the ability to theme the clock in ios 8. This is something that a lot of people where wanting and @coolstarorg jumped right on the task.
It looks like we are seeing more tweaks fix what should be done in Winterboard but we have yet to see a update for.
So if you want to theme your clock get ClassicClock from Cydia now.
