While editing TTs for Imaginary Trains, I think it'll be a very useful feature if we can "offset" the entire TT by XX hrs YY mins in one shot.
Let's...
more... say we make a 08:00 to 23:00 TT with 15 intermediate halts. We figure this TT looks good, but the slot is odd. Now I want to adjust the slot to 6:30 - 21:30 with the same intermediate halt pattern, there's no way to do it without painstakingly changing timings at all 17 stations.
Doing this manually is very very cumbersome while offsetting a list of numbers through a website feature should be simple yet incredibly helpful.
