Time entry reports show week-long time entries using the buttons to scroll through the weeks.
Time entries will not show for future dates nor dates prior to the project start date since these recordings are not allowed. Entries shown will be at least 5 minutes, the smallest allowable time entry.
Depending on the settings of a user's project permissions, they may be able to see entries from all project members, entries from just a subset of members, or just their own entries. Project owners manage the project permissions for project members.
