Time would indicate that there is a concept of a sample rate, which isn't always true and not every block is told what the sample rate is, anyways, even if the items are clocked. However, the next branch does now keep track of the number of items read and written for each input/output of each block. You can get these by calling the nitems_read and nitems_written. It returns a 64-bit number of the item count since the start of the flow graph.
