This thread - with a quote from an LR4 Beta thread - says that all 6 central Basic controls in PV2012 (Exposure thru Blacks) are now image-adaptive, as were Recovery, Fill Light, and Clarity in previous versions:

Whether they are suitable for creating a Timelapse sequence without significant flicker is entirely subjective and up to you - and of course, dependant on your specific images & how they change over time. Sorry, not much advice beyond try PV2012, and revert back to PV2010 if you get too much flicker.
