Some map statistics are based on the departure date to calculate your achievements and you might have to change it to reflect your actual journey. This date is actually the timestamp of the very first waypoint of the tracking track. Here is how to change it.
Open the map editor on DashboardNavigation Map https://www.skipperblogs.com/dashboard/map-editor
Locate the tracking track and click on the waypoint edit button
This will bring the track to the edition mode. Then locate the starting waypoint which that is displayed with a green flag. Hover your mouse over the circle and click on the green edit button 
In the popup change the waypoint's timestamp to the desired departure date, then click OK . Finally click on the save button in the floating bar to commit your changes. That's it!
