# These services typically only provide a created time and a last modified time
# for each item for general queries. This is not enough to determine if there
# 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).
