You can find a lead by searching within the date/time range in which they were uploaded to the system. You can use the Search by Lead Loaded Date Time section to conduct this search.
Simply choose a start for your time range via the Date Start field, either by entering a date and time manually or by selecting a date by clicking the calendar icon to reveal a datepicker tool.
At the bottom of the calendar, you’ll find a clock icon which you can use to select a time. Once you’ve set the start time, you can use the Date End field beside that to choose an end date and time for your date range.
