The essential difference between aggregate counters and time series is that aggregate counters perform an irreversible reduction when an event occurs (summing, taking the maximum, updating the timestamp), storing the result and discarding the raw event, whereas time series retain time-ordered sample points, allowing differences, slopes and moving averages to be computed afterwards.
