If an animation starts on the impl thread before it starts on the main thread, we currently clobber the synchronized start time. This is a bug.

The comment from your test would go well here as well.

one statement per line

Looks OK but try to get rid of the new member if you don't really need it.

we don't really need a bool, do we? m_startTime is initialized to 0 and can only become non-zero by a setStartTime() call or code internal to CCActiveAnimation, so would it be enough to just check for 0?

That's true. Removed. (Also, I had to update the unit test because I was setting the time to 0 and expecting hasSetStartTime() to be true.)
