It SHOULD be updated accordingly to the mobile position on the route.
To clarify the issue, I plotted a route with each waypoint at 10NM from the previous one.
With a boat sailing 10kt (10NM per hour), at WP2 you should be 1hr after departure, at WP2 2hr after departure, at WP3 3hr after departure…
At starting 0.00 it is OK

Between WP2 and WP23, time should be 1.00, not 0.00

Between WP3 and WP4 time should be 2.00 not 1.00

Between WP4 and WP5, 2.00 is obviously wrong

Back between WP2 and WP3, 3.00 is wrong and should be 2.00

You can check this during a multi-day trip. You will find that the date and time are inconsistent, especially if you check the date and time in forward and backward positions.
