Schedule length in time units.

[inkelyad]

Right now I am writing small patch: convoys will calculate how much time it take to make full schedule and return to first stop.
But.. How it is called? Round-trip time?

[Junna]

Scheduled time? 

[inkelyad]

Parch is here.
I am still need proper terminology for variable names and GUI.

If I understood inkelyad right, then trip total time would be the best. Trip total time is possible also for no-cyclic (no-round) orders.

Scheduled time? 

I don't think so. Your idea would fit better to case if trip order could be set exactly - station by station.

I think that "round trip time" is the best designation, as the phrase "round trip" is used in English even if the journey is not actually circular.

Another vote for 'round-trip time' from me! This will be a very useful feature.
