This dialog allows a user to define a time interval that is used to filter species records.
Once you have specified the time interval, click on the Apply button to apply the filter. As a result, the map will update, possibly displaying only a subset of the previous grid squares and the Date Filter icon will now be enabled (e.g. changes from greyed out to highlighted). Please note that date filter is applied to all species currently displayed on the map.
The dialog also allows a user to clear the date filter by clicking the Reset button.
