What's the full date range used for Explorer reports?

When you create an Explorer report, you can specify a date range as one of the report parameters (for example, when creating a Charge Back chart by using the Date Range field under Reports & Logs > Explorer Reports > Charts, or when creating a custom chart by using the event_time option). IBM® Spectrum Symphony generates the report using a default date query range from midnight (00:00 o'clock) of the start date, to midnight (00:00 o'clock) of the end date. For example, if you select to create a report from 2017-1-1 to 2017-1-7, the report will use data from 2017-1-1 00:00 (midnight on January 1, 2017) to 2017-1-7 00:00 (midnight on January 7, 2017).
