Your reasoning is backwards: different time bases is precisely the
reason we need the option of timestamps with a common reference frame.

With the situation you describe, the application that captures the two
cameras can detect that one is faster than the other and duplicate or
skip frames as necessary. Without a common timestamp, it is not
possible.
