Progressive Ports/Port Changes over time

[Pipit]

I am wondering if there is a way to time-stamp ports, just like ships and cargo have a time stamp on them that indicates what dates they become available.

I ask this because, obviously, certain ports do not become open until certain years to international shipping--and of course, ports change over time as they expand to meet growing demands.

Anyways, just an interesting thought on giving the game a bit more dynamics.

yes indeed there is a date field in the xml files, but I need to find a dynamic way to disable the ports in the program
