Cla/licenses already are OK and the build error is an error not due my changes.

I'm not sure how this optimizes getting the current time. Can you explain?

Actually, the method will return corrupted values. The method first stores the current time into a long variable and then return the contents of the long variable. Unfortunately, long assignment isn't atomic so the returned values can be corrupted.
