I think the right solution is to add a start_date tag with a date in the future. This way renderers can change rendering automatically when the date arrives. If you don't know the exact date, use a best guess. Date format doesn't seem to be specified. I would use YYYY-MM-DD format. Perhaps we should allow just YYYY and just YYYY-MM for cases where we don't know more accurately e.g. I know the M1 opened in 1959, but I don't know which month or day. Perhaps we could also allow clarification after the date e.g. start_date="2007-10-01 Approximately" or something.
