  # These services typically only provide a created time and a last modified time

  # was activity in a given time period. So, we first query for all things created
  # before end and modified after begin. Then, we get the details of each item and
  # check those details to determine if there was activity in the given period.
  # This means that query time scales mostly with (today() - begin).
