[MapServer-users] getfeatureinfo works from mapserver but not via mapcache

[Trygve Aspenes]

OK so I was a bit inaccurate. The time value comes from the default 
value in the mapcache xml tileset dimensions config,

I think this is happens here:

https://github.com/MapServer/mapcache/blob/main/lib/service_wms.c#L883-L893

and it looks to me if no value for the dimension is set then the default 
values us used. Seems OK, but why is not my time value not handled.

I guess I need some digging. Is the param and dimmension->name maybe 
case sensitive?
