For example, if you have a 10Hz clock, and call stream.update() at
t=0.91, it will compute 10 samples (for clock edges 0.0, 0.1, 0.2,
..., 0.7, 0.8, and 0.9). And then if you ask the stream what its
- current end time is (via stream.sample_time()), it will say t=1.0,
+ current end time is (via stream.end_time()), it will say t=1.0,
which is in the future, because it knows it will hold that last
sample until 1.0s.
