FileStorage generally guarantees to create a monotonically increasing sequence of tids, even if the system clock "goes backwards".  However, BaseStorage.__init__() initializes self._ts from current time, so if the system clock jumps backwards (a lot!) between opens, the first tid generated after an open can be (also a lot) smaller than the last tid actually used.
