The table batch_time contains the time period for which data is
downloaded for each batch. Each line contains one time period, the
type of the batch (i.e., control or object) and the id of the
batch to which the time period is assigned. Time frames take the form
"YYYY-MM-DD YYYY-MM-DD". Time periods are added automatically through
the function add_keywords. The function start_db exports the
table batch_time as objects time_control and time_object
to .GlobalEnv.
Example data for the table batch_time is available as R object
example_time.
