obsolete: ensure all markers have a date

Obsolescence creates a sparse DAG mostly composed of a lot of small independent
chain of markers. Date is the only simple and "reliable" way to sort them. The
existence of a date is now enforced at creation time as I'm more and more
convinced that date will have a key role in obsolescence markers exchange.
