On ‘history’, the start and end date/time pickers seem to mess each other up. Both date/time pickers try to pick a RANGE of dates, makes it almost impossible to use if the time range you’d like is over a month in span.
The ideal way to fix this would be to change the date/time picker to pick only a SINGLE date/time, not a range.
Then use the start date/time picker to pick the start date/time, and the finish date/time picker to select the finish time; that makes logical sense to me. This is so frustrating, I find it almost impossible to use.
